Appositive Phrases

Question

Could the following sentence be determined as an appositive phrase?

"Each programming language, such as Java, Python, Ruby, and HTML, has their own functionality and rules that can accomplish truck loads of tasks and problems. "

Answer 1

There is no appositive phrase in that sentence. I assume that you're referring to the phrase "such as Java, Python, Ruby, and HTML." I would probably construe that as a prepositional phrase, treating "such as" as a preposition. (FWIW, Merriam-Webster considers a phrase with "such as" to be an idiomatic construction.)

You should be aware that there are other problems in the sentence. For example, the pronoun adjective "their" does not agree in number with its referent ("each").
