The correct spelling of the phrase "watch its" can sometimes cause confusion. The sound /ɪts/ indicates that it is a possessive form of "it." However, many people mistakenly include an apostrophe and write "watch it's." This is incorrect because the apostrophe indicates a contraction of "it is" or "it has." To avoid confusion, it's important to remember that when using the possessive form of "it," there should be no apostrophe. The IPA phonetic transcription of "watch its" is /wɑtʃ ɪts/.
