Meaning and Definition

A medical event in which a pregnancy ends naturally and involuntarily before the fetus is viable, typically before 20 weeks gestation.

The natural, non-deliberate termination of a pregnancy, also referred to as a miscarriage. This is a biological event distinct from an induced (therapeutic or elective) abortion.

Dialectal Variation

British vs American Usage

Differences

The term is standard in medical contexts in both dialects. In everyday non-medical speech, 'miscarriage' is overwhelmingly preferred in both. No significant spelling or structural difference.

Connotations

Identical clinical connotations. Both see a strong shift towards 'miscarriage' in general discourse due to the potential for 'abortion' to be misunderstood or cause distress.

Frequency

Slightly higher frequency in American medical texts, but the preference for 'miscarriage' in public discourse is equally strong in both varieties.
