`  == Atypically / atypical ==  Hi, I changed 'unusual' into 'atypically', because an adverb is gramatically required at that spot and 'unusually' has different connotations.  Later, you changed 'atypically' into 'atypical' thus making it an adjective again; and I just changed it back (before having checked the history, sorry; should've done that first).  You wrote in your summary that 'atypically' sounds awkward.  I suppose that you feel the same about any adverb, like 'unconventionally' and so on.  I suppose that more editors feel that way; after all, there was an adjective there in the first place.  Should we maybe rephrase it follows? : ``He did not immediately join the Communist Party after the consolidation of the revolution, becoming a member only in 1941, which is atypical for a Soviet military officer.`` In this construction, an adjective is required, and I hope we can both agree that it is not awkward.
