All, spelled a-l-l, is pronounced /ɔːl/. The a carries the /ɔː/ vowel, and the double ll marks one /l/, not two. We all passed the test. One boundary: the homophone awl is also /ɔːl/ but spelled a-w-l; US dictionaries may print /ɔl/ without the length mark /ː/.
Using it
All is spelled a-l-l and pronounced /ɔːl/. The a carries the /ɔː/ vowel sound, and the double ll marks a single /l/, not two.
We all passed the test. A short sentence showing the spelling in use.
One boundary: the homophone awl is also /ɔːl/ but spelled a-w-l, naming a tool for piercing holes. If you hear /ɔːl/ and a tool is meant, write awl. Some American dictionaries also print all as /ɔl/ without the length mark /ː/; the /l/ ending is the same, only the vowel notation differs.
One spelling trap
One trap: the homophone awl, a tool for piercing holes, is pronounced /ɔːl/ exactly like all but spelled a-w-l. If you hear /ɔːl/ and a tool is meant, write awl.
A transcription variant: some American dictionaries print all as /ɔl/ without the length mark /ː/. The /l/ ending is the same in both systems; only the vowel notation differs, so both forms point to the same spoken word.
