Questions & Answers about No quiero toser en la videollamada.

Why is it no quiero toser and not no quiero toso or no quiero que toso?

In Spanish, when both verbs have the same subject (here, yo), the second verb normally stays in the infinitive:

• No quiero toser. = I don’t want to cough.

So:

• No quiero toso is simply ungrammatical. After quiero, you don’t conjugate the next verb if it has the same subject.
• No quiero que toso is also wrong; with que, you would need the subjunctive: no quiero que tosa, but that usually means I don’t want him/her/you to cough, not I don’t want to cough.

So to talk about yourself, you use no quiero toser, not a que-clause.

Could I say no quiero que tosa instead of no quiero toser?

Grammatically, no quiero que tosa is correct, but it normally refers to someone else:

• No quiero que tosa en la videollamada.
  → I don’t want him/her/you to cough on the video call.

Spanish speakers don’t interpret no quiero que tosa as I don’t want to cough; the subject of tosa is understood to be another person.

To talk about yourself, use the infinitive: no quiero toser en la videollamada.

Why is the subject yo missing? Why not Yo no quiero toser en la videollamada?
