Latin in the English Language


last update: 13 June 2020


TV quiz shows, etc. are full of questions about the meaning of Latin words and phrases, and in particular those that have become embedded in the English language. In some cases understanding the Latin or Greek origin of a word can help find the answer.

So there are Latin (and Greek)
roots, stems, prefixes, suffixes and phrases that can be found in English. This webpage will try to collect the most frequently used, i.e. the ones we should know and not some rare scientific or medical term of Latin origin.

A simple Latin
root in English might be voc, as in vocal or convocation.
A
stem is just a root often with a prefix or suffix to make it a fully understandable word, e.g. both tie and untie are stems, but voc above is not a full word.
A simple
prefix in English might be ante-, as in anti-inflammatory.
A simple
suffix in English might be -wise, as in otherwise.
Words can have both a
prefix and a suffix such as untouchable, where un- is the prefix and -able is the suffix with touch as the root.
A simple Latin
phrase used in English might be anno Domini.

A word of warning, there are a lot of lists of Latin roots on the Web, mistakenly include Greek root words, or just throw in plain prefixes or suffixes as well. Yet dictionaries are quite clear in differentiating between words of Latin and Greek origin (L./Lat. and Gr., and eventually Gr.-L.), and identifying prefixes (pref.) and suffixes (suff.).

When constructing these lists I was amazed at just how many words in English originate from Greek or Latin, some reports suggest that anything between ⅓ and ½ of all English words come from Greek or Latin.
