A goal is an achievement toward which effort is directed, such as getting into a certain college or running a marathon. An intention is what one means or hopes to accomplish or carry out. It is close to a plan, emphasizing what is held the mind as motivation or purpose. Sometimes, however, the word is meant to highlight distance between what is planned or wished for and what is put into action, as in the case of good intentions that fall short of producing an outcome.
To strive is to exert oneself vigorously or to try hard. When we strive for something, such as excellence or success, we are making strenuous efforts toward that goal. This verb emphasizes a tireless determination; after all, excellence and success are not easily attained. It also suggests a degree of strife, reflecting earlier, more outwardly oppositional uses of strive to mean “to rival,” “to compete,” and “to struggle vigorously, as in opposition or battle.”
If something is provided without a charge or payment, then it is free. If it is offered as a gift or courtesy, it is complimentary. Politeness is at the heart of this adjective, which also means “expressing a compliment, often one that is politely flattering.” Politeness or courtesy is also at the heart of the hospitality industry, where one is likely to encounter complimentary items, such as a complimentary breakfast or complimentary Wi-Fi. Forgoing a few syllables, a particularly lucky hotel guest might also experience a meal or service being comped, or provided free of charge.
