What does frontal mean?
'Frontal' functions primarily as an adjective meaning situated at, directed toward, or involving the front of something. Its most familiar uses span several domains: in everyday and military language it describes direct, head-on approaches ('a frontal assault'); in anatomy and medicine it identifies structures at the forehead, most famously the frontal lobe of the brain, which governs reasoning, planning, and personality; and in meteorology it describes weather systems advancing along a front. The word carries a connotation of directness and confrontation — a frontal challenge implies facing something openly rather than by stealth or from the side. Derived from the Latin 'frons', meaning forehead or leafy foliage, it entered English in the seventeenth century via medieval Latin 'frontalis'. A rarer noun form survives in ecclesiastical contexts, where an altar frontal is the ornamental cloth covering the front of an altar. Whether describing brain anatomy, weather fronts, or bold tactics, 'frontal' consistently signals what lies at or comes straight at the fore.
Of, relating to, or directed at the front; involving a direct or head-on approach. In anatomy, pertaining to the forehead or the frontal bone and lobe.
"The critics offered a frontal attack on the government's new economic policy."
Frequently used attributively in fixed pairings such as 'frontal lobe', 'frontal bone', and 'frontal system'.
A decorative covering for the front of an altar, or historically, a band or ornament worn on the forehead (also called a frontlet).
"The embroidered silk frontal was draped across the altar for the Easter service."
This noun sense is now chiefly confined to ecclesiastical and antiquarian usage.
The word 'frontal' literally comes from the Latin for 'brow' — so every time you talk about your frontal lobe, you're naming the part of the brain that sits right behind your forehead, the seat of planning and personality.

Etymology of frontal
'Frontal' derives from the Latin adjective 'frontalis', formed from 'frons', which denoted both the forehead and, by extension, foliage or leafy branches — a striking double sense in a single root. It passed into English through medieval and ecclesiastical Latin during the early modern period, first applied to coverings for the forehead or the front of altars before broadening to mean anything relating to the front. The same Latin root 'frons' underlies related English words such as 'front', 'confront', 'affront', and 'frontier', all preserving some notion of the face, the brow, or that which faces forward.
