i thought 'ó' only meant from not 'to'? is it only in a direction since that it can change to 'to'
It is used in that manner for going north and going south.
The 'ó' in 'ó dheas' and 'ó thuaidh' isn't actually the preposition 'ó''. It's derived from Old Ir. 'fa'/'fá'/'fó' meaning 'up to'. It can be confusing.
P.S. I'd prefer 'Tiomáintear....' here.
A light just went on. Thanks smrch. Don't you think grammar books for beginners should explain this? It would save a lot of doubt and indecision.
Northward vs northwards
