vigilantvsdormant
Vigilant means keeping careful watch for possible danger — alert and attentive before anything goes wrong. Dormant means temporarily inactive — alive or present, but not currently doing anything. One is wide awake on guard; the other is asleep but ready to wake.
A lighthouse beam sweeps the dark in slow, even arcs while the small ones sleep below; a harmless drift earns one measured look, but the moment an intruder slips in at the edge, the beam snaps onto it and pins it in the light.
/ˈvɪdʒɪlənt//ˈvɪdʒɪlənt/·adjectiveUnder deep snow a seed lies so still it could be a stone; now and then a faint pulse moves through it — still here — until warmth crosses the surface and it drives up a shoot, then folds back down as the cold returns.
/ˈdɔːrmənt//ˈdɔːmənt/·adjectiveBoth words describe a state of readiness, but from opposite poles of activity. Vigilant comes from the Latin vigilare, 'to keep watch': the vigilant lifeguard or immune system is defined by sustained attention paid before trouble arrives. Dormant comes from dormire, 'to sleep': a dormant volcano or seed is quiet but capable, holding its whole potential in reserve. One is awake and watching; the other is asleep and waiting — and the two often sit side by side, since you stay vigilant precisely because the danger is only dormant, not gone.
What each means
vigilant
Vigilant means awake while others sleep — from the Latin vigilare, 'to keep watch'. The vigilant lifeguard, auditor, or immune system is defined by what usually doesn't happen: the drowning prevented, the fraud caught early, the infection stopped at the gate. Vigilance looks like boring routine for hours and proves itself in a single second; the word always implies sustained attention paid before anything has gone wrong.
dormant
Dormant means sleeping, not dead — the word comes straight from the Latin dormire, 'to sleep'. A dormant volcano is quiet but capable; a dormant seed waits out the winter with its whole future folded inside it; a dormant talent, account, or conflict can wake at any time. The essential idea is preserved potential: nothing is happening, and everything still could.

How to remember the difference
Picture the watchtower and the buried seed. Vigilant is the lighthouse beam sweeping the dark — calm routine that snaps onto an intruder the instant one appears; it is attention paid before anything has gone wrong. Dormant is the seed under the snow, so still it could be a stone, sending out a faint pulse that says only 'still here' until its season comes. One is wide awake and watching; the other is asleep but not dead. If it is alert on guard, it's vigilant; if it is quiet but capable of waking, it's dormant.

They aren't strict antonyms — vigilant's opposite is 'careless' and dormant's is 'active' — but they pair naturally: you stay vigilant because a threat is only dormant. Keep dormant ('inactive but capable') distinct from 'extinct' ('gone for good'): a dormant volcano can still erupt.
