precursery examination

An assortment of inspections and tests that a pediatrician and/or child psychologist performs on a toddler during the time when he's just learning to talk, in order to determine the likelihood that he will develop a "potty mouth".

A precursery examination is all well and good, but I think that a physician should also check on how the child's PARENTS AND SIBLINGS "behave themselves" verbally, as well --- whether or not THEY exhibit a perpetually "salty" vocabulary is often a much-better indication of whether Little Junior is going to begin acquiring a "colorful" vocabulary than the results of any physical/medical tests!
