concavo-comb. form

Stress is usually determined by a subsequent element and vowels may be reduced accordingly. Some degree of stress is always maintained on the second syllable. If the subsequent element is an existing word, it is likely to retain its original stress pattern, e.g. concavo-convex n. Brit.

/kənˌkeɪvəʊˈkɒnvɛks/,

/kənˌkeɪvəʊkənˈvɛks/, U.S.

/kɑnˌkeɪvoʊˌkɑnˈvɛks/,

/kɑnˌkeɪvoʊˈkɑnˌvɛks/

in combination = Concavely, concave and ——, as in concavo-ˈconcave n. concave on both sides. concavo-ˈconvex n. concave on one side and convex on the other, and thinnest in the centre.
