"Joined the meeting" or "Joint the meeting"? [closed]

Solution 1:

https://dictionary.cambridge.org/dictionary/english/joint and its Oxford equivalent define the verb joint with examples such as "to joint something - to cut meat into large pieces". In a related construction, jointed also occurs in phrases such as "double jointed", to describe some unusual flexibility of anatomy. Otherwise, joint is given by the dictionaries as a noun of various meanings.

The use of joint as the past participle of join is not justified by any reference I can find. The past participle of join is joined. The written form of what you hear your colleagues saying is therefore incorrect.

It may be that, in speech, the "d" at the end of joined is coming out unvoiced as in joint rather than voiced as in joined.
