[TeenTimesTwo]

Phenolphthalein how to say it?

fen ol al aine

How do we do the phth bit in the middle? (y9 Science Acids & bases)

[stokeymum39]

feen olp thaline. hope that makes sense. :)

[NotCitrus]

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

[TeenTimesTwo]

stokey

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?

[TeenTimesTwo]

Citrus Why 'thy' not 'tha' ?

[DixieFlatline]

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 www.dictionary.com/browse/phthalein suggests ignoring the 'ph' part exists entirely is acceptable.

[TeenTimesTwo]

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

There’s a sound button you can play.

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

[TeeBee]

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

[christmaschristmaschristmas]

feen - al - thy - leen

[TeenTimesTwo]

Thank you all.

[worriedaf]

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

[JumpersForGoalposts]

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

[PurpleDaisies]

Fee nol thay lean for me.

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

[DixieFlatline]

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.

[WTFIsAGleepglorp]

Fee nol tha leen

[TeenTimesTwo]

Thank you.

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.

[HettySorrel]

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

[PickAChew]

Pheenol tharlin

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

[MeetOnTheledge]

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