Etymology
The word 'hatch' has a dual lineage in English, both stemming from a common Germanic root. The noun, meaning a door or opening, derives from Old English hæcc, related to Dutch hek meaning 'fence' or 'gate'. The verb, meaning to emerge from an egg, is from the Middle English hacchen, which likely evolved from the concept of an opening or a means of egress. This semantic connection is clear: just as a hatch is an opening in a deck or wall, to hatch is to make an opening in an eggshell to emerge. Over time, the verb's meaning expanded metaphorically to include the secret development of plans, as if they were being incubated.
Analysis
This is a simplex word of Germanic origin. The Old English form hæcc referred to a half-door or grating. The core concept of an opening or a means of egress connects to the verb's meaning of emerging from an enclosed space (an egg).
