The Word Poem by JJ Evendon

I'm searching for a word,
a word that is universally heard.
A word that sometime is used in a love song.
A word that's always right in meaning and never wrong.
A word that is commonly understood.
A word that spells – 'hey I'm good'.
A word that can be softly spoken or said out loud.
A word that makes you stand up, be counted and proud.
A word that has meaning beyond single measure.
A word that describes many joyous moments of pleasure.
What is this word?
- This word that has much to say?
I can't think of one. Is that 'OK'?
