Not exactly.

Emotions exist. You feel them. I feel them. Most people feel them unless they've suppressed them sooo far into their subconscious that they don't have a conscious recognition of it. We can know how someone else is feeling by reading their body language and tying that to our personal experience of how we express those feelings. No linguistics necessary.

Language is just an easier, more clear way of communicating these fundamental facets of human existence

You feel them, but do antisocial animals feel them? Or are emotions derived from mental concepts developed socially through evolution?
