228. Several endings denoting place are much like case-endings; some words formed with them may be taken either as adverbs or as nouns.
-ι, -θι, -σι (at or in) for the place where [locative]
-θεν (from) for the place whence [ablative]
-δε, -σε, -ζε (tο or toward) for the place whither
The ending -δε is added to the accusative (cp. accusative of limit, § 533); -ζε seems to be for -σδε, -δε being added to the accusative plural; -ι may be regarded as forming a locative singular, -σι a locative plural.
| οἴκοι (§ 14.a) at home | οἴκοθεν from home | οἴκαδε homeward | 
| ἄλλοθι elsewhere | ἄλλοθεν from elsewhere | ἄλλοσε else-whither | 
| Ἀθήνησι in Athens | Ἀθήνηθεν from Athens | Ἀθήνᾱζε to Athens | 
| Ἐλευσῖνι at Eleusis | Ἐλευσῑνόθεν from Eleusis | Ἐλευσῖνάδε to Eleusis | 
| ἑτέρωθι on the other side | ἑτέρωθεν from the other side | ἑτέρωσε to the οther side | 
| πάντοθεν from every side | πάντοσε in all directions | |
| θύρᾱσι at the doors | θύρᾱθεν from without | θύρᾱζε& out οf doors | 
| ἔνδοθι, ἔνδον within | ἔνδοθεν from within | |
| χαμαί on the ground | χαμᾶθεν from the ground | χαμᾶζε to the grοund | 
a. Several adverbs of the place where end in -ου.
| πανταχοῦ everywhere | πανταχόθεν from everywhere | πανταχόσε in all directions | 
| αὐτοῦ in the very place | αὐτόθεν from the very place | αὐτόσε to the very place | 
229. Adverbs of manner in -ως are made from many adjectives and some participles and pronouns; they are like the genitive plural masculine, with -ς in place of -ν.
| Gen. Pl. | Adverb | |
| σοφός wise | σοφῶν | σοφῶς wisely | 
| δίκαιος just | δικαίων | δικαίως justly | 
| ἀληθής true | ἀληθῶν | ἀληθῶς truly | 
| ἡδύς pleasant | ἡδέων | ἡδέως pleasantly | 
| εἰκώς like | εἰκότων | εἰκότως naturally | 
| τεταγμένος arranged | τεταγμένων | τεταγμένως in an orderly way | 
230. For many adjectives the neuter accusative, singular or plural, is used as an adverb.
πολύ  much
πολλά  many times
μῑκρόν  a little
μέγα and μεγάλα  greatly
πρῶτον and πρῶτα  first
231. Some common adverbs do not readily fall into classes. Thus the adverb for ἀγαθός is εὖ (well); from ταχύς the old adverb τάχα (quickly) means in prose perhaps, while ταχέως or ταχύ means quickly. From several prepositions are made adverbs in -ω.
ἄνω  above, upward
κάτω  below
ἔσω  within
ἔξω  outside
πρόσω  forward
πόρρω, πόρσω  farther on, afar
Other adverbial endings are -δόν, -δην, -στί, -εί.
ἔνδον  within
στοιχηδόν  in rοws
κρύβδην  secretly
νεωστί  lately
ἔλληνιστί  in Greek
ἀμαχεί  without fighting
πανδημεί  with full levy
232. Adverbs of number for the first three cardinal numbers are ἄπαξ (once), δίς (twice), τρίς (thrice). For higher numbers the adverbs end in -άκις.
τετράκις  four times
πεντάκις  five times
ὀκτάκις  eight times 
ἐνάκις  nine times
εἰκοσάκις  twenty times
ἑκατοντάκις etc.
On the same model are made others, like πολλάκις (often) from πολύς, ὀλιγάκις (a few times, seldom), πλεονἀκις (more times), ὁσάκις (as often as).
233. Other adverbs of number, commonly denoting division, are:
μοναχῇ (μόνος, μοναχός)  singly, in one way only
δίχα and διχῇ  in two parts, doubly
τρίχα and τριχῇ  in three parts, triply
πολλαχῇ  in many ways 
πανταχῇ  in every way
234. Adverbs derived from adjectives, and some others, are compared like adjectives; for the comparative the neuter accusative singular is used, for the superlative the neuter accusative plural.
235. Some adverbs of place have the comparative and superlative in -ω.
