Likewise is a versatile adverb that emphasizes similarity. Sometimes it is closer to “also" or "in addition,” and other times it means “similarly” or “in the same way.” It is commonly found with the verb do, as in someone urging another to do likewise, or do the same. And lastly, there’s the conversational likewise, which sometimes stands alone and is functionally equivalent to “me too," "same here," or "right back at you."
The adjective decisive is used to describe important moments or actions that put an end to controversy or clarify a path forward—things that decide an outcome. It’s also applied to outcomes that are indisputable, as a decisive defeat, and to circumstances that point overwhelmingly toward a particular outcome, as a decisive lead in votes.
To find something is to locate or obtain it. To encounter something is to come upon it unexpectedly. Those who find something are usually looking for it, and may be delighted or relieved to find it. Those who encounter something—not so much! Confrontation and conflict accompany encounter in many contexts because the word entered English poised for battle; its earliest sense was “to meet in conflict,” as in “We will encounter the enemy at dawn.” Today, encounter is used less to talk about daybreak adversaries, and more about unforeseen obstacles and difficulties.
