[v] quantus, -a, -um │ how much / many / great
- aliquantus, -a, -um: somewhat; considerable (amount)
- aliquantum (adverb): to some extent
- aliquantō (adverb): somewhat; a little; with the comparative: aliquantō longior │ a little longer
[vi] ubi│ where > alicubi: somewhere

[viii] quālis, -e│ what kind > (Mediaeval) aliquālis, -e: of some / any kind > (Mediaeval) aliquāliter: in some / any way; to some extent
ali- is possibly a truncated form of alius (other):
ibi: there > alibī (alius + ibi): somewhere else (the word you need, of course, if charged with murder; you need to have been somewhere else i.e. you need an alibi)
