"Seth has a t-shirt."
Translation:عِنْد سيث تي شيرْت.
Thanks for letting us know, NeNe. Always helpful to hear from native speakers. It might have to do with the sometimes ambiguous English words "shirt" and "t-shirt," which can in some contexts be used inter-changeably, although a 't-shirt' is more informal. A common way to refer to 'shirt' in MSA/Fus7a is قميص, which looks a lot like Spanish camisa. (Similar to "shoes": صبّاط // zapato, whereas in Fus7a حذاء is common. Analogously, 'sneakers' in English is more informal than 'shoes' but can be used interchangeably. There's a discussion of shoes in global Arabic here: https://forum.wordreference.com/threads/all-dialects-shoe-shoes.1272771/) One of the ways to say the informal item of clothing called a t-shirt is تي شيرت, but I have no doubt that قميص can also be found. Have a lingot for helping us.
