呢句英國文法有無錯?

He is not available to play the football with you.

有無錯?錯左既唔該幫我改返啱佢丫~~
He is not available to play football with you. ( 多咗個 the, 踢波冇指明要踢邊個波, 所以冇 the 字)
A有d事唔得閒同你踢足球。
A has something to do that he is not available to play football with you.

hi... ur sentence is right. u also can say in another ways ...
1. he doesn,t have time to play the football with you
2. he can,t play the football with you because he has something to do

He isn't free to play football with you

Not any question. That's a right sen.
