Combine and consolidate both bring things together, with a difference in aim. Combine is to bring separate things together into one set. Consolidate is to draw scattered things into one stronger, more solid whole, or to make a position firm. Combine simply joins; consolidate joins in order to strengthen.
Both gather, but consolidate adds strength and solidity. Combine brings separate things into one set, and there it stops. Consolidate, from Latin com- 'together' and solidus 'solid', gathers scattered things specifically to make them firmer, stronger or harder to shift — you consolidate debts into one loan, consolidate power, consolidate your gains. You combine two lists; you consolidate several accounts to steady your finances. One joins; the other joins to fortify.
combine
To combine is to bring two or more things together so they work or count as one — combine ingredients, combine forces, combine two datasets. From the Latin com- 'together' and bini 'two by two'. What is combined is pooled for a purpose, but the parts often stay distinguishable, unlike things that merge or fuse into a single body. As a noun, with the stress moved to the front, a combine is the farm machine that combines reaping, threshing, and gathering into one pass.
consolidate
To consolidate is to make many into one solid — the Latin solidus sits unhidden in the middle of the word. Companies consolidate scattered offices; armies consolidate gains before advancing; the sleeping brain consolidates the day's learning into memory. The trade is always the same: a dozen small, loose holdings exchanged for a single firm one. What is consolidated stops being a collection and becomes a structure — and structures, unlike collections, do not blow away.

Ask whether the joining is meant to strengthen. Combine just brings things into one set — berries and oats folded into a bowl. Consolidate draws scattered things into one solid whole that is harder to move — loose tiles locking into a slab that barely shifts when shoved. If things are simply gathered together, that is combine; if they are gathered to make something stronger or firmer, that is consolidate.

Combine simply joins; consolidate joins to strengthen or steady, and often carries the idea of making something firmer or more secure. Both are usually transitive. Consolidate suits finance, business and power ('consolidate debts', 'consolidate power'), where combine would lose the sense of fortifying.
A valuable pair for business, finance and politics essays. Use combine for plain joining — 'combine the datasets', 'combine two roles' — and consolidate when the joining strengthens or secures something — 'consolidate debts', 'consolidate power', 'consolidate its market position'. Consolidate also means to make firm on its own (consolidate the gains), a sense combine lacks. Both take an object; the nouns are combination and consolidation. Reaching for consolidate signals a precise, higher-register choice in the right context.
