A woman generally has a wider pelvis, broader hips, and larger breasts than a man. These characteristics can facilitate pregnancy, childbirth and breastfeeding.
From Middle English womman, from earlier wimman, wifman, from Old English wīfmann (“woman”, literally “female person”), a compound of wīf (“woman, female”, whence English wife) + mann (“person, human being”, whence English man).
What does it mean to be a woman? What it means to be a woman varies from one individual to the next. Because gender is a social construct, it is influenced by social factors, including experiences, expectations, cultures, and feelings. These factors often make up one's gender identity.
