Words once said can't be unsaid. Teagan takes that old idea and, instead of reaching for a proverb, borrows the vocabulary of a chemistry lesson. The poem never says who spoke the words or what they were, so the cause stays blank and the damage takes over. Its central idea is that a hurtful moment doesn't end when it's over. It sets off a process that keeps running out of sight, and the worst part is that the process doesn't seem to change anything.
The first line sets the terms: "irreversible words like an irreversible reaction." The word "irreversible" appears twice in one line, almost a stutter, as if the speaker is stuck on the one fact that matters. Then comes a pair of blunt fragments, "one way street. no way back." The speaker has already used a chemical image and now adds a road image, as though one metaphor can't carry the weight. The full stops chop the thought into pieces that can't be argued with.
"its a catalyst to spark combustion" is where the science gets loose. A chemist would object that catalysts speed reactions up and are not used up themselves, and they don't usually start fires. Yet the looseness works. You could even read the real definition as a bonus: a catalyst comes through unchanged, just as the spoken words stay the same while everything around them burns. Then the poem gives a single word a whole line: "burning." It reads like a flare going up. The next line widens it to "soul and body burning," so the damage is both emotional and physical.
What follows is the poem's loneliest moment: "no one sees and no one hears." Fire is normally the most visible, noisy thing there is, so a fire nobody notices is a contradiction. The parallel phrasing is flat and drained of drama, which makes it feel more final.
At this point the imagery shifts from flames to teeth. "its gnawing away from the inside out" turns the damage into something slow and animal-like, working patiently where no one can see. This line also supplies the poem's one clear end-rhyme, since "out" is answered by "doubt" in the next line. That is the only place the sound clicks into place, and it ties the hidden location of the pain to the doubt it breeds. The grammar then slips. "the beginnings to doubt. / doubt the half life should last much longer" repeats "doubt" at the end of one line and the start of the next, and without capitals it is hard to tell whether it is a noun or a command. That uncertainty seems fitting, since doubt is hard to pin down.
"Half life" is the poem's cleverest borrowing. In science it measures how long it takes for half of a substance to break down, so it implies decay that is slow and measured. Look at how time stretches across the poem. It begins with the instant of a spark, and by the end we are counting in half-lives. "decay. decay." repeats like a tolling bell. Then comes the question the poem has been heading toward, alone on its line: "forever?"
The answer is a quiet anticlimax: "it seems to stay the same." "Decay" and "stay" rhyme, which lets the final line close with a click, but the content is bleak. Decay should mean change, and the speaker finds none. Pain that is supposed to wear away just sits there. The one hedge, "seems," leaves a thin gap for doubt in the other direction, since perhaps things only look unchanged, but the poem doesn't push through it.
Formally, the poem is free verse with no regular metre. Lines run from a single word to about eight syllables, and the short ones work as held breaths. Everything is lowercase and "its" has no apostrophe. Whether or not that was deliberate, it gives the text the feel of a private note rather than a performance.
The poem is worth studying because it shows how technical language can express what ordinary feeling language struggles with. It refuses to offer comfort and ends in a stalled, unresolved present. It also leaves open who the speaker is hurting or being hurt by, which makes it easy for many readers to step into.
