Splay and spread both go outward, from different anatomy. To splay is to angle the ends of one thing out and apart while the base stays put — fingers splay from a palm, tripod legs splay from a hub, roots splay from a trunk. To spread is to extend over a wider area — butter, maps, news, disease — no anchor required; something simply covers more ground. Splay fans what is attached; spread covers what it reaches.
Spread is one of English's great general-purpose verbs — Old English sprǣdan, and a thousand years of butter, blankets, rumours and epidemics later it goes anywhere, literal or figurative. Splay is a specialist with a tidy history: it clipped itself off medieval 'displayen', to unfold, and kept a single geometric job — ends angling outward from a common base. The base is the whole difference. Splayed fingers are still one hand; a splayed tripod is one machine standing wider. Spread accepts no such anchor: the ink that spreads across a page has no centre it answers to — the stain is simply everywhere it managed to go.
splay
To splay is for the ends of a thing to fan out and apart from a common point — fingers splay on a window pane, a foal's legs splay for balance, tripod legs splay to hold a camera steady. The word is a medieval clipping of display, 'to unfold', and it often keeps a hint of the ungainly: limbs splayed where they landed rather than arranged. Where things spread to cover ground, they splay from a base they still share.
spread
To spread is to extend outward until you cover more ground — butter over toast, fire across a field, an idea through a crowd. It is an old word (Old English sprǣdan) and an irregular one: the past tense and past participle are both spread, never 'spreaded'. It works both ways — you spread the news, or the news spreads — and its great academic use is 'the spread of': the spread of a disease, of misinformation, of a movement across a region. Where widen and dilate grow a single line or opening, to spread is to disperse across a whole surface.

The tripod and the ink. The tripod splays: three ends swing out and apart, but every leg keeps its grip on the hub — the fan exists because the base holds. The ink spreads: no hub, no legs, just territory gained in every direction until the stain is simply larger. So ask whether the outward movement has an anchor. Ends fanning from a joint they never leave: splay. Coverage growing with nothing holding the middle: spread.

Splay's real workplace is the participle: splayed fingers, splayed legs, a ladder's splayed feet — the posture, once assumed, is what the word mostly describes. Spread grew extra lives splay never did: a noun (the spread of a disease, a magazine spread, a betting spread) and a whole idiom shelf (spread the word, spread yourself thin). And where spread goes abstract without effort, splay stays resolutely physical: panic spreads through a city; nothing about panic can splay.
