How would I say ‘act accordingly’ in Latin? This would be an instruction to act in a manner appropriate to circumstance.
To a single person:
ita te geres.
'You will conduct yourself accordingly.'
To a group:
ita vos geretis.
'You will conduct yourselves accordingly.'
If you wish to be a little less forceful:
ita te geras. / ita vos geratis.
'Please conduct yourself / yourselves accordingly.'
Or if you wish to be a little more forceful:
ita te gerito. / ita vos geritote.
'You shall conduct yourself / yourselves accordingly.'
