What does tu toque mean in spanish?

'Toque' is either the preterite or present subjunctive form of 'tocar', to touch.

(i) Preterite if there is an accent on the final 'e', otherwise (ii) present subjunctive.

(iii) It is also a masculine noun, with many meanings, incl. 'touch, turn, peal, etc.'

I think the most likely possibility is (iii) a noun (in e.g. a game) 'your turn'

If pronounced 'too tawKAY' (i) (preterite), it would mean 'you touched'

If 'too TAWkay' ((ii) (subjunctive), possibly 'may/let you touch'
