Learn English – `Where’s` usage in spoken English

grammatical-number

One often hears native English speakers use constructs such as "where's my trousers" or (from this forum in another post) "where is my parents and mothers?"

Is that a case of spoken grammar differing from written grammar, a case of specific variants of English from different regional areas, or just a very frequent error in English (and given the frequency of occurrence are we bordering on a change in spoken grammar)?

The question is not about the "logical" aspects but more about actual usage.

I wanted to add my approval of the previous answer as an English teacher and native English speaker.

"Where's" is the form most people actually use when speaking. It would sound strange to a native speaker to hear "Where is my trousers?" Saying "where's my trousers" is fine, but the correct grammar as you know would be "Where are my trousers?"
