Correct spelling for the English word "Pernancy" is [pˈɜːnənsi], [pˈɜːnənsi], [p_ˈɜː_n_ə_n_s_i] (IPA phonetic alphabet).
There seems to be a spelling error in the word you provided - "Pernancy." However, assuming you intended to refer to "Pregnancy," I can provide a 200-word dictionary definition:
Pregnancy is a natural biological process that occurs in female mammals, including humans, during which a fertilized egg develops into an embryo and subsequently into a fetus within the mother's uterus. It is initiated by the union of a sperm and an egg in a process called fertilization, which takes place typically in the fallopian tube.
During pregnancy, hormonal changes occur in the mother's body, causing various physical and emotional modifications. These changes include missed menstrual periods, breast enlargement, morning sickness, fatigue, increased urination, mood swings, and food cravings. Additionally, a woman's body experiences significant anatomical transformations to support the growth and development of the fetus, such as the expansion of the uterus, increased blood volume, and the formation of the placenta.
The duration of human pregnancy is approximately 40 weeks, divided into three trimesters. Each trimester is marked by distinct developmental milestones for the fetus, which can be monitored through regular prenatal care. The process of pregnancy culminates in childbirth, where the baby is delivered through the mother's birth canal or, in some cases, via cesarean section.
Pregnancy is an essential and transformative period of life that involves maternal care, proper nutrition, regular medical check-ups, and emotional support for both the expectant mother and her growing baby.
