six · sex
Short /ɪ/ versus short /ɛ/ — getting these right avoids embarrassing mix-ups.
⚠️ Common mistake
This is one of the most common mistakes Spanish speakers make. Confusing these words can cause serious embarrassment. Practice carefully!

mouth shape
jaw UP, tongue HIGH — short relaxed /ɪ/ before the x
six
/sɪks/
vowel length

mouth shape
jaw LOWER, mouth wider open — /ɛ/ is lower and more open than /ɪ/
sex
/sɛks/
vowel length
Key difference
For six, your tongue is HIGH — almost touching the roof of your mouth, jaw up. For sex, your jaw drops slightly and the vowel feels wider and more open. Put your finger under your chin — you should feel it move DOWN for sex.
