What I, a common phrase, can be replaced with various synonyms depending on the context of its usage. For instance, "What I wish to convey" colloquially can be changed to "My message is". Consider, "What I want to do" can be expressed as "My intention is to". To describe thoughts, "What I think" can be substituted with "In my opinion" or "As far as I know". Moreover, "What I mean" can be interchangeable with "I intend to say" or "What I am suggesting is". Hence, utilizing appropriate synonyms can effortlessly convey the intended meaning and tone, propelling the conversation forward.
