A subordinate or auxiliary statement or proposition used in an argument or proof, often serving as a step towards establishing a larger conclusion.
He struggled with the big problem, but he found a small truth. This helpful, minor statement, a useful lemma, showed him how to bridge a gap. It wasn't the main answer, but this little proof made the final, larger conclusion feel within reach.
The botanist painstakingly documented the tiny spore's reproductive cycle. Each observation, a small finding, felt like a precious lemma, a building block. Without these tiny proofs of function, she'd never explain the plant's survival in the toxic mudflats.
The farmer stared at the patchy soil, a knot in his stomach. His neighbor's success depended on a tricky harvest calculation. He'd proven a small, helpful fact about crop rotation, a necessary lemma, to show his neighbor how to manage the difficult field and save his livelihood.
To prove my cat, Reginald, is the supreme ruler of the universe, I first established a simple lemma: all fluffy creatures are inherently bossy. This tiny, fluffy fact was crucial, a stepping stone toward the grand conclusion that Reginald, with his magnificent floof, must therefore be in charge of everything.
Bartholomew the badger, trying to prove his sock collection was sentient, presented a hilarious lemma: "If a sock can sing opera, it must also crave cheese." The judges, though amused, found this subordinate statement insufficient for the larger conclusion of sock sentience, but everyone agreed Bartholomew's logic was pure, cheesy gold.
She felt a surge of triumph. After hours wrestling with the problem, this tiny, overlooked lemma finally unlocked the entire proof. It wasn't the grand finale, but this crucial step was the key to reaching the bigger, satisfying conclusion.
The old mechanic squinted at the schematics, a frustrating knot tightening in his gut. He needed to prove the carburetor's fuel line was blocked. First, he'd establish the lemma that clean fuel made the engine run smooth. Without that little truth, the whole engine rebuild would be pointless.
The entire expedition hinged on proving this single point. Every calculation, every scanned artifact, was designed to support our main theory. This small, established fact, a necessary lemma, became the linchpin, the unshakable foundation upon which our desperate gamble for funding would finally stand or fall.
My neighbor's dog, a fluffy menace, claimed my prize-winning petunias were an affront to caninekind. To prove it, he presented a lengthy, convoluted lemma about the superiority of squeaky toys. The judges, bewildered by his logic, eventually just awarded him the biggest squeaky toy as a bribe, accepting his little argument as a step towards peace.
Sir Reginald, a badger of discerning taste, attempted to prove his cat, Bartholomew, enjoyed opera. He presented a minor conclusion: Bartholomew purred during a Puccini aria. This small, supporting idea, a crucial lemma, was meant to build towards the grander point that Bartholomew was, in fact, a closet tenor.
He finally saw the path to the solution, but it was obstructed. He needed to prove a small, intermediate point first—a tricky little lemma—before he could tackle the main problem. Without that confirmed step, the entire argument would crumble.
The engineer stared at the complex circuit diagram, blocked by an intricate coupling issue. He meticulously worked through a smaller, supporting problem, a crucial lemma, proving its stability. This fundamental lemma, once established, finally unlocked the path to solving the overarching system failure.
The seasoned archivist, brow furrowed, stared at the faded script. To prove the document's provenance, she needed to establish a critical lemma: that the peculiar ink composition only appeared in royal scriptoria after the 1480s. Without this, her entire case for its authenticity would crumble.
The aspiring wizard, struggling with a particularly convoluted spell, muttered, "This prerequisite incantation, this tiny, helpful lemma, is supposed to make the fireball *not* ignite the librarian's wig. Fingers crossed it doesn't just turn him into a sentient teacup instead."
My attempt to convince the sentient mold colony that disco music wasn't a viable form of communication hinged on a rather obscure mathematical lemma about mycelial vibrations. This little supporting statement, proving that their pulsating rhythms were more akin to a leaky faucet than a coherent message, was crucial. Without that lemma, my argument for them to switch to Gregorian chants would have crumbled, leaving me to endure an eternity of pulsating goo.
His thesis hinged on a complex theorem, but first, he had to meticulously prove a crucial lemma. This ancillary proposition, a stepping stone of sorts, was absolutely vital for the ultimate verification of his grander assertion. Without its successful substantiation, his entire edifice of thought would undoubtedly falter.
The prospect of successfully calibrating the chroniton dampeners seemed insurmountable, a veritable Gordian knot of quantum entanglement. However, my colleague presented a crucial lemma, a tangential but verifiable principle regarding temporal flux stabilization. This auxiliary statement, though not the ultimate solution, proved indispensable, a stepping stone allowing us to finally achieve the desired, albeit precarious, temporal equilibrium.
The alchemist, meticulously scrutinizing the glyphs, realized the penultimate step in transmuting the basalt required a forgotten lemma, a small, pivotal truth that, once proven, would irrevocably unlock the grander objective. Without that auxiliary proposition, the entire alchemical edifice would remain stubbornly inert.
The esteemed mathematician, perspiration beading on his patrician brow, presented a surprisingly facile lemma regarding the migratory patterns of sentient teacups. This ancillary assertion, a mere stepping stone, was crucial for his far grander, albeit wholly preposterous, theorem that explained the inherent melancholy of soufflés.
Professor Quibble, known for his egregious syllogisms regarding sentient fungi, presented a particularly abstruse lemma: that the bioluminescent glow of a mushroom indicated its profound existential ennui. This auxiliary statement, though seemingly nonsensical, was cunningly designed as a foundational step towards his grander, albeit bewildering, conclusion about fungal philosophical discourse.
