Pinyin initial: "ju"

Mouth Mechanics (step-by-step)

The syllable ju is made of two tightly linked parts: the j- initial + the -u (actually “ü”) vowel.

1. Start with a “front-of-the-mouth smile tongue.”
   Put the front and middle of your tongue high and close to the roof of your mouth, a bit behind your front teeth.
   • The tongue shape is closer to the position you use for “ee” in see than for “oo” in too.

2. Keep the tongue tip relaxed and low.
   The tip of the tongue should not press hard against the teeth ridge like an English “d” or “t.” The action is higher, more toward the middle of the tongue.

3. Make a tight “j-ish” friction, not a heavy English “j.”
   Let air squeeze through the narrow gap between the high tongue and the roof of the mouth, creating a light, tight hissy “j” sound.
   • It’s not the thick, bouncy English “j” in jump.
4. Immediately round the lips for the vowel (this is crucial).
   While keeping the tongue high and forward (like “ee”), round your lips as if you were going to say oo.
   • This combination (tongue like “ee” + lips like “oo”) is the key to the ü-type vowel written as u after j.
5. Keep it smooth—one continuous syllable.
   Don’t separate it into “j + yoo.” It should be one clean syllable: ju.

English Approximation (what to use, and how to modify it)

English doesn’t have the exact j + ü combination, but you can get close with these approximations:

• “jeep” — use the “j” onset (the very beginning), but make it lighter and tighter (less “d” impact).
  Match: the start of the word.

• “cheese” — use the tongue position you feel during “ee”, but round your lips while keeping that tongue shape.
  Match: the “ee” tongue posture (then add lip rounding).

• “you” — use the lip rounding from “oo,” but do not use the English “y” glide as a separate sound.
  Match: the lip shape, not the full vowel movement.

Quick build (very practical):
Say “ee” (as in see). Freeze your tongue there. Now round your lips like oo without moving the tongue back. That vowel is the target “u” in ju.

Common Mistakes (English-speaker traps)

• Mistake 1: Saying “joo” like June.
  That uses the English oo (tongue pulled back). In Mandarin ju, the tongue stays forward and high.

• Mistake 2: Adding a clear “y” sound: “jyoo” / “j-you.”
  Mandarin ju is not two parts (“j” + “you”). It’s one tight syllable with the ü-type vowel.

• Mistake 3: Making the English “j” too heavy.
  English “j” often has a strong, bouncy “d” quality. Mandarin j is tighter, lighter, and more “hissy.”

• Mistake 4: Letting the lips stay flat.
  Without rounding, you drift toward something like ji. Lip rounding is essential.

Comparisons and Caveats (important contrasts)

A) ju vs zhu / chu / shu

• ju uses a front, high tongue (an “ee-like” tongue posture) and a tight, hissy consonant.
• zhu / chu / shu are made farther back with a more retro feel (tongue shape farther from the “ee” posture), and they pair with a more typical “u/oo-like” vowel feeling.
• If your ju starts sounding “thicker,” “darker,” or “farther back,” you are probably drifting toward zhu/chu/shu.

B) ju vs ji

• Both start with the same j- quality.
• The difference is the vowel:
  • ji ends with an ee-like vowel with unrounded lips.
  • ju ends with an ü-like vowel: same forward tongue, but rounded lips.
• A reliable self-check: If your lips are not rounded, it’s probably not ju.

C) ju vs qu / xu

• These three are a “family” and feel similar in mouth position (all use the ü-type vowel after these initials).
• The difference is the initial:
  • j is tight and light.
  • q is like a tighter “ch,” typically feeling more forceful.
  • x is more purely “hissy,” like a soft “sh” made with the tongue very forward.
• Keep the vowel consistent (the ü-type vowel) and change only the consonant quality.

D) What happens when -e / -an / -n / -ong are added

The j- part stays essentially the same; what changes is the ending:

• jue-: keep the same j and rounded-front (ü) setup, then open into -e smoothly (no extra “y” inserted).
• juan-: same setup, then flow into -an with the “a” colored by the rounded-front start (avoid making it “jwan” like English Juan).
• jun-: same ju core, then close into -n (don’t turn it into “June”—keep the tongue forward).
• jiong-: begins with the same j family feeling but quickly includes a y-like glide into -ong; don’t replace it with English “jong” with a heavy back “j.”

The consistent theme: Mandarin j is a tight, forward, hissy “j,” and after j, the written u is the ü-type vowel (forward tongue + rounded lips).
