Hi again, Alexander! Continuing my previous reply to you:
Can you pluralize these words?
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].
tooth _teeth_
Correct.
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].
cactus _cactuses_ (although I vaguely remember there also
is another form). But my variant is also correct, is it?
Yes. I'd say "cacti", but "cactuses" is widely accepted too. :-)
goose _geese_
Correct.
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. :-)
mouse _mice_
brother-in-law _brothers-in-law_
wife _wives_
woman _women_
All correct.
index _indexes_
memorandum _memorandums_
millennium _millenniums_
Yes... or indices, memoranda, and millennia.
9/10 correct! Very good.... :-)
