Feen-olf thy leen. With the F in the middle dropped most of the time.

what is the h after the p doing then?

Also is the th a 'th' or 't' sound?

Is the a as in cat or as in /ay/

and line' as in washing line? or leen as in Pauline?

Phenol and phthalein are individual parts of the word (and words themselves) so neither should have bits chopped off and clearly stuck on the other in pronunciation. I hadn't come across the word 'phthalein' before but suggests ignoring the 'ph' part exists entirely is acceptable.

ps Are you both 'guessing' or does one of you 'know'? smile

There’s a sound button you can play.

According to my chemistry a level teacher it is fee-nol thay-leen. No ph sound.

I say it the same as Stokeymum. And that's how my chemistry lecturer used to pronounce it.

I’m a chemistry teacher and I say it phee nol fay leen. Doubting myself now!

I've always thought it was pronounced fee-nol thar-leen.

PurpleDaisies Fri 23-Nov-18 15:29:38

Fee nol thay lean for me.

I have now said it so many times in my head it is weird.

The phonetic guide on the Oxford Dictionary link gives both fee-nol-tha-leen and fee-nol-thay-leen (translated into layperson phonetics...) as accepted versions.

Fee nol tha leen

Thank you. smile

DD hasn't a hope of learning how to spell it, but at least I know how to say it and I can discuss its meaning with her, and so she can come up with something vaguely near enough to be recognisable if she needs to write it down.

Fee-nol-tha-leen is how I was taught.

What wonderful thread. This has taken me back to my school time and made me look up what exactly phenolphthalein is.

MeetOnTheledge Thu 24-Jan-19 22:44:04

Fee-nol-tha-leen (I'm a chemist). A lot of people say fee-nol-thay-leen though.
