Gloss “gaer” by Eldamo Import

Is that horrifying or horrified? I'd say awful rather implies the former while fearful implies the latter, but it hardly means both, does it?

Fearful can mean both, see www.merriam-webster.com

So, Gaer means both too? I'm just asking because causing fear and being in fear is quite a difference to me; does one suffix (-ā) really cover both in Elvish?
