Here's how we usually show long and short vowel sounds in phonetic transcription, which uses a more standardized set of symbols:
Long Vowel Symbols:
* Long A: /eɪ/ (as in "say")
* Long E: /iː/ (as in "see")
* Long I: /aɪ/ (as in "my")
* Long O: /oʊ/ (as in "go")
* Long U: /uː/ (as in "you")
Short Vowel Symbols:
* Short A: /æ/ (as in "cat")
* Short E: /ɛ/ (as in "bed")
* Short I: /ɪ/ (as in "big")
* Short O: /ɑ/ (as in "hot")
* Short U: /ʌ/ (as in "cup")
Important Notes:
* These phonetic symbols are used in dictionaries and linguistics. You might see them if you're studying phonetics or a related field.
* There are other ways to mark long and short vowels in written English, such as putting a macron (¯) over the vowel for long sounds or doubling the vowel (like "ee" for long "e"). These are not universally used, though.
