I often get tripped up over the TH sound.
The word Maths is a plural contraction of mathematics.
I can pronounce "math" accurately with the TH sound, but I just don't know how to sound off "maths" to combine the "th" sound and the "s" sound.
It will come off my tongue sounding off as "mats" but the th sound would be lost.
If I blend the TH and S sound together and sound it off, it sounds "ma-f- ss", is this a good way to say this "maths" word ?
For me, it sounds unnatural and more than a mouthful.
I study applied math and pure math; so I'm studying maths.
'Mathematics' - like physics, rheumatics, aerobics, isometrics .... - is singular; it just happens to have an s on the end, like kudos.
PS - You may find this interesting: Pronunciation of English th - Wikipedia, the free encyclopedia ; the pronunciation /mæfs/ is not right, but if you do it that way you're not alone. 'TH fronting' is a feature of many dialects.
Yes, there's no way around the fact that pronouncing it exactly involves a quick tongue. But try not sticking it out too far in this case, before the s.
Or, just say it as we do in AmE: math.
