I'm having a debate between my friends and my English teacher, it came up during a practice conversation in class and I said that "How does my soul taste" and they proceeded to correct me by saying that it's said "How does my soul tastes" given the fact that it is referred to as "He/she/it", what is the correct way to say it?
In English, there can be only one conjugated verb that agrees with the subject.
- Did he really eat a dozen chocolate bars at one sitting?
- She has already done her homework.
- We were not consulted on this project.
Your friend's sentence
*How does my sole tastes?
would then have two conjugated verbs, which doesn't work in English. It must be:
How does my sole taste?
I presume you are talking about a type of fish, sole, rather than the soul.
How does my soul taste?
How tastes my soul?
In the second example, which is suggested by your friends' and teacher's understanding of the idea, the auxiliary verb should be omitted, to match the change of form for the verb tastes.
To test it:
- He tastes. He does taste.
- She tastes. She does taste.
- It tastes. It does taste.
The use of the auxiliary verb is optional; it's mainly a matter of style and context or emphasis.
