Spoken English contractions of did with what why how etc

[sdudah]

Hello,

It is common to find contractions in spoken English with did as in (why'd you do that?)
so the question is: can I generalize the example above to make contractions like :
- why'd he do that ?
- what'd he do that ?
- how'd he do that ?

What about the other pronouns like they and it ?

Thanks for the help

Two things to remember about contractions:

1. Don't use them in formal writing.

2. If in doubt, don't use them at all.

The examples you give (except for the second one, which is incorrect) will be seen and heard in informal writing and conversation only.

Thank you Rover; happy to read your reply.
Sorry, the second example came out of mechanical typing & fatigue. It should be typed without that, namely "what'd he do?"

Since ('d) could go with (you and he), I do not see any problem with the use of other pronouns i.e. (they and it). However, I am not quite positive since I did not find any direct statements on them. I must not resort to inference when I could get direct answers.

Your response is much appreciated

You can use 'd with they and it:
Why'd I/you/he/she/it/we/they do it.
