5. Position of adverbs

Certain adverbs, known as mid-position adverbs (e.g sometimes, always, never, often, definitely, certainly], are usually placed after auxiliary verbs and before other verb s: He has certainly done it. However, when we wish to emphasize the auxiliary verb, we put most mid-position adverbs before it instead of after: He certainly has done it. In British English this second construction is always emphatic. In American English, however, the adverb is frequently placed before the auxiliary, even when there is no intent to emphasize.
