Synonym discussion

Sense: adjective/1

All three words relate to the forward-facing side of something, but they differ in usage and formality. 'Front' (B1) is the simplest everyday adjective: 'front door', 'front row', 'front page'. It can appear both before a noun ('the front wheel') and after a linking verb ('the door is front'). 'Frontal' (B1) is more formal and almost always appears before a noun — you cannot say 'the damage is frontal'; you must say 'the frontal damage'. 'Forward' (B1-B2) describes movement or direction toward the front, not fixed position: 'a forward seat' means a seat facing the front, but 'a frontal seat' means a seat at the front. 'Anterior' (C1) is a technical term restricted to anatomy and biology — 'the anterior surface of the heart'. Use 'front' for everyday speech, 'frontal' for formal or technical descriptions of position, and 'anterior' only in scientific writing. For example: 'The front door is locked' (everyday), 'The frontal section of the building faces the square' (formal description), 'The anterior chamber of the eye contains fluid' (medical).

Etymology

LatinFrenchEnglish

Frontal comes from the Latin word 'frontalis', meaning 'of the forehead', which was formed from 'frons' (forehead, front). In the mid-1600s, English borrowed it as an anatomical term for the forehead bone. By the 1800s, the word broadened to describe anything located at the front of an object or space. The weather-related meaning appeared in the early 1900s as meteorology developed the concept of air-mass boundaries called 'fronts'.
