用法筆記

Unlike most English prefixes, 'oligo-' attaches primarily to Greek or Latin stems to form technical vocabulary. It does not attach freely to everyday English words — you cannot say *'oligobook' or *'oligocar'. Look for it in specialist terms from political science (oligarchy), economics (oligopoly), biology (oligodendrocyte), ecology (oligotrophic), and biochemistry (oligosaccharide).
