How Do You Spell CONCAVOUSLY?
Pronunciation: [kɒnkɐvˈa͡ʊzli] (IPA) 
The word "concavously" is spelled with a "c" instead of "k" because it is derived from the Latin word "concavus". The "ou" combination represents the "oʊ" diphthong sound. The "s" is added to the end of the word to create an adverb form. The IPA phonetic transcription for "concavously" is /kənˈkeɪvəsli/, with the stress on the second syllable. It means that something is concave in shape, curving inward like a hollow sphere or a cave.
