It seems debatable if a diphthong is one sound. By IPA rules they are indicated by two symbols. So the mentioned trigraph "igh" is not a good example. It does not use three letters to represent one sound−Woodstone 18:07, 2005 Mar 28 (UTC)
- It is one sound phonologically, just as an affricate is. It's arguable whether ay for /ai/ or tš for /tʃ/ are digraphs (I don't know whether they technically count or not), but ie for /ai/ and ch for /tʃ/ do count. The same thing applies for trigraphs. You might want to argue that igh is the vowel i followed by a silent gh, but since night is not pronounced nit, I don't know if this is viable. kwami (talk) 23:23, 5 August 2008 (UTC)
Is 'scratch' a trigraph? The 'scr' being the possible trigraph. What about the 'tch' at the end is that one too?
"Scr" is one sound but 3 phonemes, so I don't THINK that would work, but I'm no linguist. I do think the "tch" would work.

- Agreed. A trigraph is not analyzable. scr /skr/ = s /s/ + c /k/ + r /r/. But you can't analyze tch as t + c + h or even t + ch. kwami (talk) 23:23, 5 August 2008 (UTC)

Digraphs and trigraphs are quite common, but do you know of any tetragraphs in any languages?? Georgia guy 01:24, 17 June 2006 (UTC)
- In French there are lots of tetragraphs, caused by verb endings. In ils disent (they say) the ent is silent, forming a tretragraph sent representing [z]. In the past tense this becomes ils disaient where the pentagraph aient is pronounced [ɛ]. −Woodstone 10:09, 17 June 2006 (UTC)
- I've added it to the template under trigraph. However, please correct me if I'm wrong: since the apostrophe is not a letter in Swahili (unlike, say, Hawaiian), I don't think ng’ is technically a trigraph. But I'm not going to worry about it for now. kwami (talk) 23:23, 5 August 2008 (UTC)
Note: German <sch> is pronounced /ʃ/ while Swedish <sch> is pronounced /ɧ/. — Knyȝt (talk) 22:26, 26 October 2014 (UTC)
