VOCABULARY: words ending in EX

I often play a game as I'm trying to go to sleep in which I try to rhyme words ending in various combinations of letters. For two nights in a row, I was trying to finds words ending in ex and managed to find quite a few. However, I realised that there were plenty more that I was missing so today I determined to discover some more. Here are some of the more common words arranged alphabetically:

A: apex, annex

B: biconvex, biflex (meaning bent in two places) 

C: circumflex, codex, convex, cortex, complex, cybersex 

D: desex, duplex, diplex (pertaining to the simultaneous operation of two radio transmitters or to the simultaneous reception and transmission of radio signals over a single antenna through the use of two frequencies. 

E: the ending itself (ex) seems to be the only known word 

F: flex, fourplex (four family apartment house) 

G: googolplex (a number that is equal to 1 followed by a googol of zeros and expressed as 10^10^100 where a googol is a number that is equal to 1 followed by 100 zeros and expressed as 10^100).
