How many words are in the following statement?
You put the grr in grrl.
Most, if not all, English speakers would say no less than four.
Some would say four, arguing that grr has no distinct semantic content, being simply a guttural utterance, and that grrl is nonstandard.
Some would say five, arguing that grr has no distinct semantic content, but grrl is an alternative spelling of girl that carries a meaning distinct from the standard spelling.
And some would say six, accepting that in this context grr has a distinct meaning.
What qualifies as a word is not so clear cut, even if we have commonly understood criteria for making that determination.
