Every once in a while, we can all get a bit grumpy. When someone is grumpy on a regular basis or in a particularly argumentative way, they could be described as cantankerous. Cantankerous folks are disagreeable and often contentious. Being four syllables, cantankerous is a loftier-sounding word than grumpy, an expressive word akin to a grunt with origins in the phrase “humps and grumps.” Cantankerous, on the other hand, was probably formed from a Middle English word that meant “quarrel” or “contention.” A machine can be personified humorously as cantankerous if it does not operate smoothly, and similarly, so can an animal that displays opposition or irritableness.
Generosity refers to a readiness or liberality in giving, and sometimes to an overall spirit of kindness. Generous giving, when it involves gifts or money, can be called largess. Largess can also refer to the gifts themselves. At the root of largess is the word "large," so one way to think about it is that those who show largess are characterized by the largeness of their contributions, monetary or otherwise. Most commonly, you will see largess used in the public works sense, denoting a sense of superiority or higher rank on the part of those bestowing it.
To hope for something is to desire it with only some expectation that it will happen. The verb aspire nudges desire toward action, implying an eagerness and drive to make it so. The work that goes into making an aspiration real may even leave you breathless. After all, aspire comes from the Latin verb meaning "to breathe upon" or "to pant after." Consider the lofty aspirations of the dog who pants after the squirrel; much like Fido, when we aspire to something, we are working to attain it.
