Form and rules
How it works
Frequency adverbs usually go before a main verb but after be: I usually drive; I'm usually early.
With auxiliaries, many mid-position adverbs go after the first auxiliary: She has never been; They will probably arrive.
Manner adverbs often go after the verb/object: She explained the problem clearly.
Place normally comes before time at the end: We met at the office yesterday.
Front-position adverbs can organize or emphasize information: Fortunately, nobody was hurt; Last year, sales increased.
