a blueprint folding itself into a body before anyone asks permission.
means An organism in its earliest stage of development, from fertilization until the major body structures begin to form (in humans, roughly the first eight weeks).
from From Greek 'embryon,' meaning the young of an animal still in the womb or egg — literally 'that which grows within,' built from 'en-' (in) and 'bryein' (to swell, to be full, to teem). The same swelling-with-life sense surfaces in the verb's other children; to 'bryein' was to burst with growth. The word came into English through Medieval Latin 'embryo,' carrying its quiet promise of something ripening unseen.
