Stand-in language supercut, based on the assumption that Common is English:
Abyssal = Serbo-Croatian
Aquan = Tagalog
Auran = Inuktitut
Celestial = Tiberian Hebrew
Draconic = Classical Greek
Dwarven = Icelandic
Elven = Sindarin
Giant = Old Norse
Gnome = Finnish
Goblin = Armenian
Halfling = Dutch
Infernal = Classical Latin
Orc = Kazakh
Ignan = Persian
Sylvan = Welsh
Terran = Sumerian
Undercommon = Tibetan
Generally, I prefer to use less familiar languages, to play to the suspension of disbelief as much as possible, but use Latin script to demonstrate orthography and phonology suitable for the theme of the fantasy language. The exceptions are: Dutch as Halfling, for something comparatively close to English/Common; Classical Latin as Infernal, for connotations of legalism and esotericism; and recognisably Nordic languages as they already have strong mythological (essentially fantastic) associations with Dwarves and giants. I go for Sindarin as Elven to have something elegant but not French, as that is a.) too familiar to me and b.) pretty inelegant in its various French Canadian forms.
Aklo I do not ascribe a language to, as it makes no sense to me to give a human-made natural language to inhuman things with alien or deranged mindsets. The existence of Aklo is flat-out questionable to me.
