6dwn. the answer appears to be RACKET but surely the correct spelling is racquet?

Racket is accepted as a variation

I'd saying RACKETS as a plural as it is used in both games

[The_Necromancer]

I put RACKETS as a plural as the question refers to both tennis and squash.
the Americanisation 'RACKET' does seem have become common, especially as the prime search engine, Google Chrome, does not have the facility for UK English spelling, merely the trans-Atlantic gibberish. But that's no excuse for the MoS to do so. I would generally use RACQUET.
