Morphology
The phrase can be reasonably interpreted from its parts as 'east but slightly toward north' — a B1 learner who knows 'east', 'by' (near/next to) and 'north' should infer a direction a little north of due east. However, the specific navigational convention and exact angle (one compass point) are specialized and not fully predictable from everyday use of 'by', so full comprehension requires background knowledge.
Etymology
East by north is a compass phrase from sailors who used a wheel with many small points. It literally meant a small step from east toward north, so sailors used east by north to show a very exact 'direction'.
