Short i /ɪ/ or long ee /iː/? ship and sheep
Short answer: The short vowel /ɪ/ (in ship, sit, bit) is relaxed and short. The long vowel /iː/ (in sheep, seat, beat) is tense, with the lips spread and the tongue high, and it is longer. Changing the vowel changes the word: ship and sheep, sit and seat, bit and beat are different words.

Examples in sentences
- The ship is big.
ship /ʃɪp/: short vowel. - A sheep is in the field.
sheep /ʃiːp/: long vowel. - Please sit on this seat.
sit /sɪt/; seat /siːt/. - I feel ill.
feel /fiːl/; ill /ɪl/. - Leave it where you live.

Common problems
- Making both vowels the same: If ship and sheep sound alike, listeners cannot tell the words apart.
- Making the short vowel too long: Keep /ɪ/ short and relaxed. Do not pull it into /iː/.
- Trusting the spelling: ee and ea usually give /iː/ (see, eat), but not always (head, great).
For Vietnamese speakers
- Vietnamese does not use vowel length to tell words apart, so learners may merge /ɪ/ and /iː/. Practice by making the long vowel clearly longer and the short vowel very short.
- A mirror helps: the mouth is more spread for /iː/.

Questions
Is the length the only difference?
No. /iː/ is also tenser, with the lips more spread. Length and tension work together.
Do ee and ea always sound /iː/?
Mostly, as in see and eat, but there are exceptions, for example head /hɛd/ and great /greɪt/.
Is the same difference in other vowels?
Yes. Short and long pairs also exist in sets such as full and fool.
