Hi again, Alexander!  Continuing my previous reply to you:

AH>  Can you pluralize these words?

AK>  I will not ask Google. ;)


           This is an "open-book" exam with no time limit, meaning you are at liberty to consult Uncle Google or not as you prefer... [chuckle].



AK>  tooth  _teeth_


           Correct.



AK>  lens  _it is the plural form_


           No... the plural is "lenses".

           In a wonderful example of synchronicity, you posted an example not long afterwards about somebody who lost a contact lens during a cricket game. Whenever I learn a new word I often notice it again somewhere else... [grin].



AK>  cactus _cactuses_ (although I vaguely remember there also
AK>  is another form).  But my variant is also correct, is it?


           Yes.  I'd say "cacti", but "cactuses" is widely accepted too.  :-)



AK>  goose  _geese_


           Correct.



AK>  moose (a new word for me) _the same form in plural_


           Ah.  I should have guessed the term would be unfamiliar, but you're right.  It's a species of large deer (Alces alces) found in North America & in Eurasia.  When the inhabitants of the New World were asked "What's that?" they answered by saying something which sounded +/- like "moose".  When people from Sweden were asked the same question they answered with something which sounded +/- like "elk".  As a result, "moose" = "elk" in British English.  :-)



AK>  mouse  _mice_

AK>  brother-in-law  _brothers-in-law_

AK>  wife  _wives_

AK>  woman  _women_


           All correct.



AK>  index  _indexes_

AK>  memorandum  _memorandums_

AK>  millennium  _millenniums_


           Yes... or indices, memoranda, and millennia.


           9/10 correct!  Very good....  :-)
