Brute - Vine's Expository Dictionary of New Testament Words

Brute

[ 1,,G249, alogos ]
translated brute" in the AV of 2 Peter 2:12; Jude 1:10, signifies "without reason," RV, though, as J. Hastings points out, "brute beasts" is not at all unsuitable, as "brute" is from Latin brutus, which means "dull, irrational;" in Acts 25:27 it is rendered "unreasonable."
