A text is ambiguous when it can honestly support more than one meaning at the same time, and neither meaning cancels the other out. This is different from confusion. A confusing sentence just needs a second, more careful read until it resolves into one clear meaning. An ambiguous line stays open even after careful rereading, because the writer built it that way on purpose. Ambiguity asks a reader to hold two or more readings at once and decide, through their own thinking or through conversation with someone else, which meaning fits best, or whether the meanings are meant to sit together.
Writers reach for ambiguity when a single, settled meaning would flatten what they are actually trying to say. A poem that states its point outright closes the door once the reader reaches the last line. A poem that leaves a key phrase open keeps that door swinging, because different readers, or the same reader on different days, can walk through it differently. That openness is not the writer being careless. It takes more control to build a line that supports two real readings than to write one that only supports one. Ambiguity works because language itself is layered. A single word can carry a literal sense and a symbolic one, and a skilled writer lets both stay active without picking a winner.
Marilyn Dumont, who is Métis and a descendant of Gabriel Dumont, builds her 1996 poem "The Devil's Language," from her collection A Really Good Brown Girl, around exactly this kind of ambiguity. The poem's central phrase, "the devil's language," never settles into one meaning. Read one way, it names standard English, the "Great White way of writing" that Dumont says judged and silenced her throughout school. Read another way, by the poem's final stanza, it names Cree, her father's language and her own mother's tongue, the language she can no longer fully speak or sing in. Dumont never tells the reader which reading is correct. She lets both stay true at once: English has been used as a weapon against Cree speakers, and Cree has been branded as something foreign and suspect by English institutions. A reader who picks only one meaning and stops there has not finished reading the poem. The ambiguity is the point. It forces the reader to sit with both meanings and ask what it costs a person to lose a language, no matter which side of that history did the naming.
This is why a poem like Dumont's rewards conversation more than a poem that simply states its argument. Two readers can each notice a different half of the ambiguity and only reach the poem's full weight by talking it through together, testing their reading against someone else's questions. That is not a weakness in the poem. It is the whole reason ambiguity exists as a tool, and it is exactly what this lesson asks you to practice: reading something that will not resolve on its own, and using real questions to work out what it means.
Sit with these questions before you open the poem. When Dumont writes "the devil's language," which language do you think she means on a first read? Does that answer change by the poem's final lines, and if so, what changed it?
