The word 'like' there is more of an indicator of vagueness than a filler. Though if it's expressed to give the speaker time to think of a number, it does have filler properties, in my judgement.
So these are mutually exclusive, then? Does a word being a filler restrict it from having any influence on the sentence's meaning?
Here are some definitions of "like" from Merriam-Webster and Google (which attributes its definition to Oxford Languages). Do these still count as "fillers"? Can a filler be used "to emphasize a word or phrase", "for an apologetic, vague, or unassertive effect", and "to signify the speaker's uncertainty", or would that make it a filler no more?
I'm unable to attach a screenshot for some reason, so I'm just going to post these:
- used interjectionally in informal speech often to emphasize a word or phrase (as in "He was, like, gorgeous") or for an apologetic, vague, or unassertive effect (as in "I need to, like, borrow some money")
- nearly, approximately (
the actual interest is more like 18 percent)
- used interjectionally in informal speech with expressions of measurement (
it was, like, five feet long)
- used in speech as a meaningless filler or to signify the speaker's uncertainty about an expression just used.
