Is it correct to use a tilde (~) in a paper as punctuation meaning ''sort of identical to"?
In a paper I am writing (APA style), I have a sentence like this: > Another category of common sounds found across many languages are the palato-alveolar consonants (~siblants). These include... The meaning I want to convey is that palato-alveolar consonants are very related to siblants and I add the word 'siblants' in parentheses for laymen who may not be familiar with the term 'palato-alveolar consonants'. However, I do not want to just say > palato-alveolar consonants (siblants) because they are not totally identical. Is the usage of the tilde in this case acceptable in my paper? If not, are there any other ways I can convey this information?
