The term that refers to an affix added in front of a word is "prefix." A prefix modifies the meaning of the root word by providing additional context or changing its grammatical function. For instance, in the word "unhappy," the prefix "un-" alters the meaning of "happy" to denote its opposite, making the concept clearer in context.

In contrast, a suffix is added at the end of a word to change its form or meaning, such as turning a noun into a verb or modifying tense. An affix is a broader term that encompasses both prefixes and suffixes. A compound word combines two or more words into a single term, which is a different linguistic construction altogether. Therefore, "prefix" accurately captures the idea of an affix placed at the front of a word.
