Origin of oo-
WORDS THAT USE OO-
What does oo- mean?
Oo- comes from the Greek ōión, meaning “egg.” The Greek ōión helps form the word ōophóros, meaning “egg-bearing” and is the source of the combining form oophoro-, used to indicate the ovary.
Distantly related to the Greek ōión is the Latin word for egg, ōvum, source of the related combining forms ov-, ovi-, and ovo-, also used to mean “egg.” The Latin ōvum is ultimately the origin of ovario-, used, like oophoro-, to mean “ovary.”
What are variants of oo-?
When combined with words or word elements that begin with a vowel, oo- becomes o-, as in oidium.
Examples of oo-
One example of a scientific term that features the combining form oo- is oocyte, “an immature egg cell of the animal ovary,” including in humans.
The oo- part of the word means “egg,” as we have seen. The second part of the word is -cyte, from the Greek kýtos, means “cell.” Oocyte literally translates to “egg cell.”
What are some words that use the combining form oo-?
