More tumaceous is a rarely used adjective that means more full of lumps or rounded masses. It is pronounced as /mɔː ˈtjuːmeɪʃəs/, with a stress on the second syllable. The first syllable 'more' is pronounced as in the word "more", while the second syllable 'tumaceous' is pronounced with a long "u" sound as in "tune", followed by "may", and then "shus". This word is derived from the Latin word 'tumere' meaning 'to swell', and is used mostly in scientific jargon.
The word "more" itself comes from the Old English word "māra", which means "greater" or "larger". "Tumaceous", on the other hand, is not a widely recognized English word. It is a rare technical term used in medical and biological contexts to describe something that is swollen or characterized by abnormal growths. The word "tumaceous" is derived from the Latin word "tumēre", meaning "to swell". As for the combination "more tumaceous", it suggests a comparative form of "tumaceous", indicating that something is even more swollen or growth-oriented compared to a normal or baseline state. However, it's worth noting that "more tumaceous" is not a commonly used phrase in everyday English.
