Should I use all the alternatives like "t shirts", "tshirts" and "t-shirts" in the descriptions?

Should I use all the alternatives like "t shirts", "tshirts" and "t-shirts" in the descriptions or does the algorithm see them as one thing? Should "tees" also be used?

I know some people don't use the hyphen or just write it as "tshirts",  that's why I'm asking this question.

In a description I would probably try to use one or two different ones.  The ones I would use would be different than whatever Z adds to the end of your title.  That way you have 2 or 3 descriptors for the same product across the title and description.

As t-shirts are the product... they should not be in the tags at all...

Is it a hard and fast rule that the product type should never be in the tags? If I designed a t-shirt that was perfect for a trombone player, I'd want to use the tag "t-shirt for a trombonist" for example. Would that be wrong?
