Definitions of Alter and Altar

Definition of Alter

The word “alter” is a verb that means to change or modify something. It implies making something different in some way, whether in appearance, character, or form. “Alter” can be used in various contexts, from physical modifications to changes in behavior or plans. The term is derived from the Latin word “alterare,” meaning “to make other.”

Examples of using “alter” in a sentence include: “We need to alter our plans due to the weather,” or “She decided to alter her dress for the party.” In both cases, “alter” signifies a change or modification.

The verb “alter” can be conjugated in different tenses, such as “altered” (past tense), “altering” (present participle), and “alters” (third-person singular present). Understanding these conjugations is essential for using “alter” correctly in various grammatical contexts.

Definition of Altar

The word “altar” is a noun that refers to a table or raised structure in a religious place, such as a church or temple, where sacrifices or offerings are made. It is a central element in many religious rituals and ceremonies, serving as a focal point for worship and devotion. The term is derived from the Latin word “altare,” meaning “high place.”

Examples of using “altar” in a sentence include: “The priest stood at the altar during the ceremony,” or “They placed flowers on the altar as an offering.” In both cases, “altar” refers to a specific religious structure.

The noun “altar” is typically used in a literal sense, referring to a physical structure in a religious setting. However, it can also be used metaphorically to represent a place of sacrifice or devotion in a non-religious context.

Structural Differences

The primary structural difference between “alter” and “altar” lies in their grammatical function. “Alter” is a verb, meaning it describes an action or state of being.

It can be conjugated and used in various tenses. “Altar,” on the other hand, is a noun, meaning it represents a person, place, or thing.

It cannot be conjugated and is typically used as a subject or object in a sentence.

Another key difference is their spelling. While both words share the same first four letters, the last letter distinguishes their meaning.

“Alter” ends in “er,” while “altar” ends in “ar.” This seemingly small difference is crucial for identifying the correct word in a given context.

Consider the sentence “They will alter the altar.” Here, “alter” is used as a verb, indicating the action of changing something, while “altar” is used as a noun, referring to the religious structure. This sentence clearly illustrates the structural and functional differences between the two words.
