Remember, a term that originated in Old French and Latin, has its roots in the Latin word "remembrer", meaning "to remember". This term is derived from the combination of "re-", meaning "again", and "memor", which comes from PIE root *(s)mer-(1) meaning "to retain in mind". The term's meaning of "call to mind; remind one that something exists in memory without necessarily having it present at the moment" first appeared in the late 14th century. The term "mention" for bringing something back into memory or consciousness, and its application to people, first emerged in the 1550s.

The medieval English language also had words like "hit remembreth me", which means "I remember". Similarly, the Anglo-Saxon language included a corresponding verb called "gemunan". The common practice of inserting a 'b' between 'm' and the following vowel (especially in words with silent final vowels like "number", "chamber", and "humble"), is often seen in these words.

When we use the words "remember", "recollect", and "remembrance", it implies that something exists in memory, but not necessarily that it is present in our thoughts at the time. It suggests a return of information without any particular effort being exerted. On the other hand, "recollect" implies that after some effort has been exerted, a fact or memory that was forgotten or partially lost can be recalled and brought into conscious mind. Finally, "remembrance" refers to the store-house of memories, while “recollection” is the act of selecting particular pieces from this repository.

In modern English usage, both terms have similar meanings, though "recollect" is used less frequently than "remember". In general, we use "remember" when we want to convey that we simply recall information, whereas we use "recollect" when we want to emphasize the effort put in to bring something back into our memory.

Remember"一词在日常生活中经常被使用，但其含义可能会让人感到困惑。我们经常说我们不能记住一件事情，但实际上，这意味着我们不能回忆起它。在这里，“记得”是指某件事情存在于记忆中，而不是当前的思考中，但它会自然而然地再次出现。

另一方面，“recollect”则意味着一个被遗忘或部分丢失的事实在经过一些努力后被回忆起来并出现在脑海中。这里的"recollect"可以被视为从记忆库中挑选出特定的信息。例如，当我们被要求回忆某段对话时，我们可能能够做到这一点；然而，如果要求我们回忆一个具体的事件或事实，那么就可能会有些困难。

值得注意的是，这两个词经常被混淆。例如，当我们说我们不能记住一件事时，实际上是指我们不能回忆起它。这种混淆可能会导致我们在交流中的误解和困扰。

尽管"remember"和"recollect"在某些情况下可以互换使用，但它们之间还是存在着微妙的差别。理解这些差异可以帮助我们更准确地表达我们的思想，避免在交流中的误解。
