Is it correct to use an apostrophe after the s in word years sentence She has almost 30 experience teaching languages?

No, it is not correct to use an apostrophe after the "s" in "years" in the sentence "She has almost 30 years experience teaching languages."

Here's why:

* "Years" is a plural noun. It refers to multiple years. Apostrophes are used to indicate possession or contractions, not to make a word plural.

* The sentence is missing an article. The sentence should read: "She has almost 30 years' of experience teaching languages."

The phrase "30 years' experience" is a possessive noun phrase, indicating that the experience belongs to the 30 years.
