As in the case of adjectives, not all adverbs in Greek form the comparative and superlative degree. In the same way, they form these two degrees either monolectically or periphrastically. (See also relevant section on adjectives.)
| Attribute | Value | Gr. example | Gr. tag |
| Degree | basic | akriva | AvNsBa |
| comparative | akrivotera | AvNsCp | |
| superlative | akrivotata | AvNsSu | |
