The particles show different degrees of independence as regards their position. Many are completely independent and may occupy any place in the sentence; some may occur only at the beginning (prepositive particles, as ἀτάρ); others find their place only after one or more words at the beginning (postpositive particles, as γάρ, δέ); and some are attached closely to a preceding word o<*> even form compounds with that word wherever it may occur (γέ, τέ).
