Irish 'capall' (horse) + '-án' (the diminutive, the little horse) — the little dark horse
He stands fine and dark at the roadside and waits for the drunk rider to climb on, and the ride that follows is the longest or the shortest of the rider's life depending on whether he was kind at the inn that night.
Best for A horse-form puca of the midnight road
Irish 'bóthar' (road) + sharp ending — the road-thing
He has worn the same stretch of road for a hundred years, and the locals know that anyone seen walking it after midnight is in his company whether they know it or not.
Best for A puca of the lost road
Irish 'marcach' (rider, horseman) reshaped — the rider
He carries the lost traveller home, but the rider who does not thank him at the gate is said to find the road twice as long the next time he walks it alone.
Best for A horse-form puca who carries the lost home
Irish 'adharc' (horn) + '-án' diminutive — the little horned one
He stands at the crossroads as a horned goat and does not move, and the traveller who chooses the road he faces finds trouble, while the one who turns back finds he has already gone.
Best for A goat-form puca of the crossroads
Irish 'sgiath' (wing) + '-án' diminutive — the little winged one
He circles high above the man the wind has chosen to spare, and the sailor who sees him at the masthead knows the storm will break before it reaches the ship.
Best for An eagle-form puca of the high wind
Irish 'cruth' (shape, form) + '-ach' (the one of) — the shape-one
He has worn a horse, a goat, an eagle, an ass, and a man with goblin eyes, and no one in the parish can agree on which of these is his true shape because he has worn all of them in one night.
Best for A shape-shifter puca who is none and all
Irish 'gaoth' (wind) + '-án' diminutive — the little wind
He is heard before he is seen, and the cottage that hears his laughter on the wind at Samhain knows to leave a share at the field's edge before morning.
Best for A puca who rides the wind
Irish 'toghairm' (the call, the summoning) reshaped — the calling-one
He calls a name from the dark that is not quite the name of anyone living, and the man who answers is said to be unable to find his way home for a year and a day.
Best for A trickster puca of the voice in the dark
Irish 'Samhna' (of Samhain, of November) + '-ach' (the one of) — the one of Samhain
He is busiest on the night the worlds thin, and the household that forgets his share on Samhain finds the milk cursed and the cattle wandering for a season.
Best for A puca abroad at the year's turning
Irish 'cleas' (a trick, a feat) + agent-ending — the trickster
He once bet a farmer he could empty the man's grain store by morning, and he did it by giving every grain to the poor of the next parish — and the farmer could not bring himself to be angry.
Best for A trickster puca whose cleverness is the point
Irish 'rith' (to run) + 'mir' (the play, the sport) reshaped — the running-sport
He takes the rider who mounts him on a ride that does not end until dawn, and the man who laughs through it is set down safe at his own door while the man who screams is set down in the next county.
Best for A horse-form puca of the wild ride
Irish 'aoire' (herdsman, the one who watches the flock) — the watcher
He is paid his share each Samhain and in return he keeps the wolves from the fold and the fox from the henhouse, and the family that breaks the bargain loses three lambs by spring.
Best for A puca who watches over a farm
