Abbie takes one of the most familiar phrases in English and turns it inside out in two lines. "Mother tongue" normally names the language we soak up before we can choose anything, the unexamined speech of home. When the speaker announces that "Silence is my mother tongue," what was handed down is the absence of words. The poem is about growing up fluent in not-speaking, and about the loneliness inside that fluency: the speaker can produce this language perfectly, yet "never understood a word of it."
The construction is lopsided on purpose. The first line is short, only seven syllables, and flat and declarative, with no qualification. It ends on the two heavy beats of "mother tongue," like a door being shut. The second line is more than twice as long, seventeen syllables that run on after the hinge word "but," as if the speaker has started to explain and cannot stop. That "but" works like a turn in a sonnet, squeezed into a single breath. There is no rhyme and no steady metre, which suits the subject, since nothing in the poem chimes or answers back. Even the sound is muted. The soft, gliding *l* of "silence" and "fluently" gives the line a smooth, practised surface, which is exactly how fluency should sound.
The smallest word in the poem may be the most telling. The pronoun "it" appears twice, in "speak it" and "word of it," and the poem's last word is "it." The speaker never names silence a second time and points at it with the vaguest word available. The poem ends on an unstressed syllable, fading out instead of closing with a flourish, almost as if it were falling silent itself.
The central paradox rests on a reversal of how language normally works. Children understand before they speak, but here the order is flipped: the speaker can perform the language without comprehending it, like someone reciting a prayer in a tongue they were never taught. What would it mean to "speak" silence? The poem leaves this open, but the fluency suggests something practised until it is automatic: the swallowed sentence, the changed subject, the instinct for what to leave unsaid. The claim of never understanding "a word" is also impossible to satisfy, because silence has no words. That is both the joke and the wound. The speaker lacks a dictionary for a language that cannot have one, and so cannot say what the silences meant. They might have been anger, tenderness, fear, or nothing at all. The poem withholds that answer, and the speaker seems never to have had it either.
There is a further irony in the fact that the poem exists at all. Someone who claims silence as their first language has still found words to say so. The poem can be read as a small act of translation, or as a quiet rebellion. But the word "never" is final. The speaker breaks the silence only to report that it remains opaque, and that speaking about it has not made it any clearer.
Part of the poem's significance lies in what it refuses to say. It does not tell us whose silence this is, whether the mother's, the speaker's own, or both. It does not say why the silence existed or what it cost. Because of that, the poem practises what it describes: it withholds, and the reader has to do the work of interpreting. This also lets it widen beyond any single story. Anyone who has grown up in a house, a family, or a culture where the important things went unspoken may recognise the sensation of being completely at home in a language of gaps and still being unable to read it.
Two lines are enough to hold an entire inheritance. The poem asks whether a language made of absence can be understood, or only spoken, and it leaves that question hanging in the quiet after the last "it."
