7.B The Defensible Interpretive Thesis (LAN-1.D)
A defensible thesis states an interpretation of the text that a careful reader could reasonably disagree with, along with the reason that interpretation holds. It is a claim, not a list of devices.
A thesis has to be arguable. If nobody could possibly push back on it, it isn't an interpretation, it's a fact or an observation. 'The author uses imagery, repetition, and a shift in tone' is true of the text but immune to disagreement, because it doesn't claim anything about what those devices mean. 'The trial scenes present the law as a machine that works perfectly and decides nothing' is a position. A reader could say no, the verdict does change something, and that friction is exactly what makes the sentence worth defending.
Think of the thesis as a spine. Every body paragraph has to attach to it, which means the thesis has to be built, not just announced. The reliable way to build one is interpretation plus reason: state the reading, then state why it holds. 'Inheritance is a burden because each of the legatees is worse off within five years' gives the essay both its claim and its evidence pattern before a single body paragraph starts. Without the 'because,' a thesis is just an opinion floating with nothing underneath it.
A strong thesis does more than survive counterargument, it previews a line of reasoning. 'The poem admits the loss only through its grammar, so that the stanzas can keep describing the garden while the sentences fall apart' doesn't just name devices like metaphor or enjambment, it tells you the order paragraphs should come in: first the garden descriptions, then the grammar breaking down. That's the difference between a thesis that labels and one that argues, and it's what lets commentary later explain evidence instead of just restating it.
