Hi folks. I was teaching a lesson on vocabulary and decided to teach prefixes, suffixes and roots (eg Latin and Greek).

I am not sure how you differentiate between, for example, a prefix and a root. It seems that "hydro" is a root but "geo" is not. "Bio" maybe a root or a prefix?????? Is it that a root can change spelling in an 'English' word? Any help will be much appreciated. Thanks,

Kush

Here's a start:

It depends on the meaning of the word, and of course the location of the affix, since a prefix by definition goes on the front.

'Biology'-- 'bios' is the central concept, hence the root, while 'logy' is a suffix meaning 'study, knowlege of'.

'Biorhythm'-- here the rhythm is the central concept (root) and the 'bio' tacks on the idea of life as a prefix.

Suffixes are mostly parts-of-speech makers, turning verbs into nouns into adjectives.
