Why this mattersThe same problem, at the back

The same problem as the last unit, at the back of your mouth instead of the front. Full and fool, pull and pool, look and Luke.

Fewer word pairs depend on this one, so it is less urgent than ship and sheep. But it affects a group of very frequent small words, could, would, should, good, book, put, and getting those wrong is heard constantly.

The same switch as ship and sheep, one unit later, at the back of your mouth.

What your language doesMost learners default to the long one

Again, if your language has one u sound, English has two and you will hear one.

Most learners default to the fool vowel, so full becomes fool, good becomes goood, put rhymes with boot. The words come out sounding stretched and slightly formal.

The same trap applies. This is not about length. A long and a short version of the same vowel is still one vowel to an American ear.

Common trap

Most learners default to the fool vowel, so full becomes fool and put rhymes with boot. A long and a short of the same vowel is still one vowel to an American ear.

How to make itThe same switch, one unit later

Fool. Tongue high and back, muscles tight, lips firmly rounded and pushed forward.

Full. Everything relaxes. The tongue drops slightly and comes forward a little, and the lip rounding loosens.

The picture: fool is a tight whistle shape. Full is the same shape gone soft.

The way in. Say fool and hold it. Let the tension go without stopping the sound. It becomes full. Back and forth: fooo, uh, fooo, uh.

Mirror check. On fool your lips push forward noticeably. On full they barely move.

Minimal pairsThe two words, side by side

Play each pair deliberately and feel the one difference. This is where the sound stops being abstract.

What do units 14 and 15 have in common, and why does that help?

Both are one relaxed vowel against one tense vowel, front of the mouth then back. Same instruction, same practice method. Learn the switch once and use it twice.
