Today, the universal tuning standard for most musical instruments is a definite pitch with a hertz number of 440. This means that the vibrations of that pitch are oscillating at 440 cycles per second, or 440 Hz. In music, definite pitches such as this are called tones.
Agapeo: The Greek word that refers to the love of God, one of the kinds of love we are to have for people, is agape. Agape is the very nature of God, for God is love (1 John 4:7-12, 16). The big key to understanding agape is to realize that it can be known from the action it prompts.
The word aglet (or aiglet) comes from Old French aguillette (or aiguillette), which is the diminutive of aguille (or aiguilee), meaning needle. This in turn comes from the original Latin word for needle: acus. An aglet is thus like a small needle at the end of a shoelace.
