A name that means something.
A"Trustworthy, faithful, honest." Al-Amīn ("the Trustworthy") was the nickname given to the Prophet Muhammad before revelation, in recognition of his honesty that even his enemies acknowledged.
Arabic root: ʾ-m-n — أ-م-ن, trust, security
"Ameen" is the more intuitive US spelling — it also echoes the word "Amen" familiar in Christian and Jewish usage.
