Concentrate and split are opposites. Concentrate is to draw scattered things together to one central point, to make something denser, or to focus. Split is to break or divide something along a line, often forcefully, or to end a relationship. Concentrate gathers to a point; split forces one apart into two.
One draws things to a single point; the other cleaves a whole apart. Concentrate, from centrum 'centre', gathers scattered things to a central point and intensifies them. Split, an old word for a forceful lengthwise break, drives one thing apart along a line — a log under an axe, a party over an issue. Power is concentrated in one office; a party splits over a vote. One masses things at a point; the other breaks one thing into two.
concentrate
To concentrate is to gather toward one centre until it is strong — from the Latin com- 'together' and centrum 'centre'. Scattered forces concentrate at a border; a reader concentrates on a page, pulling stray attention to one point; boiling concentrates a juice by driving off its water. As a noun, a concentrate is what is left when the water is gone: the same substance, no longer spread thin. To consolidate holdings is close, but concentrate keeps the sense of intensity growing as things gather.
split
To split is to break something apart along a line — a log splits under the axe, a plank splits with the grain, a party splits over a policy. It is more forceful and everyday than divide, and the break is not always equal. From an old Germanic root meaning 'to cleave'. Figuratively, couples split up, a bill is split, and a difference is split down the middle. As a noun, a split is the crack or division itself — a split in the party.

Ask whether things gather to a point or a whole is cleaved. Concentrate draws scattered things inward to one dense centre — light pulled to a burning dot. Split forces one thing apart along a line — a log falling open into two halves under an axe. If things gather to a point, that is concentrate; if one thing is broken sharply into two, that is split.

Concentrate gathers to a point and intensifies; split forces one thing apart along a line, often suddenly. In politics they can pair: power concentrated in one place, or a movement that splits into factions. Split ranges from wood to a couple to the bill, while concentrate stays with massing, density and focus.
