The pictograph a  is a picture of an ox head and also represents its strength. The l is a picture of a shepherd staff and also represents the authority of the shepherd. Combined these two pictographs mean "the strong authority" and can be anyone or thing of strong authority. The yoke is understood as a "staff on the shoulders" (see Isaiah 9:4) in order to harness their power for pulling loads such as a wagon or plow. Hence, the two pictographs can also represent "the ox in the yoke". Often two oxen were yoked together. An older, more experienced ox would be teamed up (yoked) with a younger, less experienced ox. The older ox in the yoke is the "strong authority" who, through the yoke, teaches the younger ox.

note: The ox head is actually the letter alef its where the greeks got their letter alpha and where we got our letter a. the shepherd staff is equivalent to our letter l. so you spell God (Al or El) and it speaks of an ox and a yoke and the letters that make the word are an ox and a yoke.

note: to the hebrews the marriage contract was considered to be a yoke. binding two people together making them one, just like the yoke does with the oxen.
