How do I pronounce 用勿着 in Shanghainese? There isn't a pronunciation for it on Wiktionary, and I don't know whether it is a fossilised or an analysable phrase, so therefore I don't know whether or not right-prominent tone sandhi applies. My guess would be:

/ɦi̯ʊŋ²² v̻əʔ⁵⁵ t͡sa̱ʔ²¹/

if it is a fossilised expression and thus right-prominent tone sandhi doesn't apply. Please tell me if I am correct. Thanks
Here is the entry for 用勿着 in《上海方言词典》on p. 304:



Text:

【用勿着】
ɦyoŋ˨˧꜖ uə?˥꜒ za?˨˧꜒꜔
⇨ ⟦得⟧ ßiɔ˥꜒ tə?˥꜒꜕

Tone letter to number translation:

ɦyoŋ²³⁻¹¹ uə?⁵⁵⁻⁵⁵ za?²³⁻⁵³

Tone sandhi is usually represented by back-to-back tone letters. So it looks like the corrected tones are:

ɦyoŋ¹¹ uə?⁵⁵ za?⁵³

Correct me if I'm wrong, because I have no idea about Shanghainese tones.

Here's an entry from a second dictionary 上海话大辞典 p. 274
