loose or limp, not densely arranged.
The term lax refers to a feature of vowels that has been argued to stem from a number of articulatory mechanisms. One such mechanism is the relaxed status of the articulators. Another possible mechanism is the non-advanced position of the tongue root during production of the vowel. In English, some lax vowels are the vowels //,//,//, and /ç/, as in mitt, met, book, and caught (in some dialects of English, the vowel /ç/ has fused with /a/. The complementary feature of lax is tense.
