Burgeon and proliferate both describe rapid growth, of different shapes. To burgeon is for one thing to put out new growth and flourish — a burgeoning industry, a burgeoning talent: it swells, gets fuller, and the writer generally approves. To proliferate is for instances to multiply — copies making more copies, until there are far too many. Burgeon fills one thing out; proliferate fills the world with many.
The mechanism differs, and so does the writer's attitude. Burgeon began as a botanical word for putting out buds, and the picture holds: a single branch thickening into leaf, one entity becoming more of itself. Proliferate comes from proles, offspring — each new instance is itself capable of producing more, which is compound growth, and that is why the word attaches so readily to things nobody wanted multiplied: rumours, weapons, paperwork. One word implies flourishing; the other implies a count getting out of hand.
burgeon
To burgeon is to grow and flourish fast — to break out into rapid, abundant growth. It began literally, from Anglo-French burjuner, 'to bud or put out shoots', and you can still feel the bud in it: a burgeoning industry or population does not just get bigger, it puts out new growth in every direction at once. It is a formal, faintly literary word, stronger than plain grow, and it lives most often as the adjective burgeoning — a burgeoning market, a burgeoning talent.
proliferate
To proliferate is to multiply at a pace that feeds on itself: cells proliferate, weeds proliferate, and so do startups, streaming services, and conspiracy theories. The word descends from the Latin proles, 'offspring' — to proliferate is literally to keep bearing offspring, which is why it means compounding growth rather than mere increase. Each new instance is also a new source. What began as one is, suddenly, everywhere — and the speed itself is the story.

| Result | fuller, flourishing | numerous, often too many |
| Attitude | approving | often uneasy |
| Origin | botanical — putting out buds | proles, 'offspring' |
| Classic subjects | industry, talent, city, career | rumours, weapons, cells, paperwork |

The leafing branch and the doubling cells. Burgeon is one thing thickening into new growth, and the word carries the writer's approval with it — a burgeoning career is good news. Proliferate is a count compounding until the field is full, and it usually arrives with unease, because each new copy makes more. Ask whether you have one thing getting fuller or many things getting more numerous. One, flourishing: burgeon. Many, multiplying: proliferate.

Burgeon has drifted from its own origins, which is worth knowing before you trust a dictionary's first sense. It began as a narrow botanical word for putting out buds — the very first stage of growth — and some usage guides still treat the modern 'grow rapidly, flourish' sense as a loosening of that meaning. The drift has plainly won: almost nobody now writes of a branch burgeoning in the strict sense. Burgeon's contrast with wither, and proliferate's with diminish, both have their own pages in the 'Related' list below.
The markable error is a connotation mismatch, not a grammar slip: 'crime has burgeoned' and 'the arts scene has proliferated' are both understandable and both wrong-footed. Keep burgeon for growth you approve of in a single subject — a burgeoning middle class, a burgeoning industry — and proliferate for counts multiplying, especially where you want a note of concern. Proliferation is the more useful noun in Task 2, since 'the proliferation of X' compresses a whole problem statement into three words.
