Words such as often and sometimes can appear in more than one place. Start with a common mid-position, then notice when a front or end position is also possible. Each exercise below names the position it wants. A different valid emphasis is not automatically a grammar mistake.

What is the verb doing?

A one-word frequency adverb tells us how often something happens. In an ordinary affirmative pattern it commonly goes before a main lexical verb: The cook usually checks the oven. Keep the verb and its object together in the pattern shown.

When be is the main verb, the ordinary mid-position comes after it: The north gate is never open at night. Different placement can signal contrast or emphasis; this is a useful default, not the only possible English order.

With the named auxiliaries in these examples, put the adverb between the auxiliary and the following verb: can often find, have often used, are usually working. These are bounded placement patterns. Other orders may change emphasis or scope; the lesson does not outlaw them.

First identify what have is doing. We always have spare blankets uses have as a lexical verb meaning possess. We have often used the east gate uses have as an auxiliary. The requested slot changes with that role.

Try the first four

Read the instruction, then choose the sentence that follows it before opening the answer. These are self-checks, not an automatic grammar score. Questions 1–6 and 8 name a slot; question 7 asks for ALL possible options. Another valid emphasis is not automatically wrong English.

  1. Choose the version with usually directly BEFORE checks, keeping the subject first.

    Context: The cook checks the oven.

    A. The cook usually checks the oven.

    B. Usually, the cook checks the oven.

    C. The cook checks the oven, usually.

    Answer and explanation

    Matches the requested position: A

    The cook usually checks the oven.

    Usually sits between the subject and the lexical verb checks in the requested ordinary mid-position.

    Other positions. B fronts usually and C uses a final/parenthetical position. They do not match this instruction; do not label them universally ungrammatical.

  2. Choose the version with never directly AFTER is.

    Context: The north gate is open at night.

    A. The north gate never is open at night.

    B. The north gate is never open at night.

    Answer and explanation

    Matches the requested position: B

    The north gate is never open at night.

    Is is the main verb be. The requested usual order is is never open.

    Other positions. A places never before be and can need a contrasting/emphatic reading. The exercise selects a named slot, not every possible English emphasis.

  3. Choose the version with often BETWEEN can and find.

    Context: The scouts can find shelter here.

    A. The scouts often can find shelter here.

    B. The scouts can find shelter here often.

    C. The scouts can often find shelter here.

    Answer and explanation

    Matches the requested position: C

    The scouts can often find shelter here.

    Can is a modal auxiliary; often occupies the requested slot before the lexical verb find.

    Other positions. A/B use other placements, potentially with different focus or scope. They are not judged wrong English merely for missing this slot.

  4. Keep the opening phrase; place often BETWEEN have and used.

    Context: Over the past month, we have used the east gate.

    A. Over the past month, we have used the east gate often.

    B. Over the past month, we have often used the east gate.

    C. Over the past month, we often have used the east gate.

    Answer and explanation

    Matches the requested position: B

    Over the past month, we have often used the east gate.

    Have is an auxiliary in this perfect construction. The task asks for have often used; it does not test which tense to choose.

    Other positions. A/C do not follow the specified slot. End-position often is possible; emphasis/context can license alternatives. No general grammaticality rejection.

Four more to try

  1. Keep the opening phrase; place usually BETWEEN are and working.

    Context: At this hour, the smiths are working.

    A. At this hour, the smiths are usually working.

    B. At this hour, the smiths usually are working.

    C. Usually, at this hour, the smiths are working.

    Answer and explanation

    Matches the requested position: A

    At this hour, the smiths are usually working.

    Are helps form the progressive here. Usually comes after that auxiliary and before working in the requested pattern.

    Other positions. B/C change placement/focus. They are not globally incorrect; C also does not keep the requested opening.

  2. Use always directly BEFORE have, with We still first.

    Context: We have spare blankets.

    A. We have spare blankets, always.

    B. We always have spare blankets.

    Answer and explanation

    Matches the requested position: B

    We always have spare blankets.

    Here have means possess and is the main lexical verb, unlike auxiliary have in question4. The requested position is before have.

    Other positions. A is a final/emphatic placement, not the requested slot. Do not treat it as a categorical grammar error.

  3. Choose ALL sentences that can express the occasional habit. No special mid-position is required; differences in emphasis are allowed.

    Context: Lena uses a boat on some trips.

    A. Sometimes, Lena travels by boat.

    B. Lena sometimes travels by boat.

    C. Lena travels by boat sometimes.

    Answer and explanation

    Accepted patterns: A + B + C

    Sometimes, Lena travels by boat.

    Lena sometimes travels by boat.

    Lena travels by boat sometimes.

    All three are possible for the stated habit. Sometimes can be initial, mid-position or final. The focus can differ; there is no exclusive mid-position requirement here.

    Other positions. All three sentences can describe the stated habit. Sometimes can go at the beginning, in the middle or at the end; the emphasis can differ.

  4. Place often at the END of the complete sentence, as requested.

    Context: The ferries cross the bay.

    A. The ferries often cross the bay.

    B. Often, the ferries cross the bay.

    C. The ferries cross the bay often.

    Answer and explanation

    Matches the requested position: C

    The ferries cross the bay often.

    End-position often is possible. C keeps the subject/verb/object together and puts often at the requested end.

    Other positions. A is a normal mid-position and B is possible fronting. Both are valid in suitable contexts; neither follows this particular end-position instruction.

A requested slot is not the only English order

Sometimes can be initial, in the middle or final. Often can also appear at the front or end in suitable contexts. Their focus may change. This flexibility does not mean every adverb can go anywhere; negative fronting and other structures are outside this lesson.

A task can request one slot without claiming every other sentence is bad English. Question7 deliberately accepts three patterns; question8 requests an end position. A sentence may miss the position requested by an exercise and still be grammatical.

Never supplies a negative frequency meaning while is remains affirmative in form in the displayed example. Never means not at any time. Words such as sometimes, often and usually do not have fixed numerical percentages.
