What does substituting mean?
Substituting means replacing one person or thing with another or temporarily taking another person’s place. It is commonly used when an ingredient, material, example, or person is used in place of the usual choice, as in “substitute honey for sugar,” and it can describe someone filling in for an absent worker or performer. The word carries no strongly positive or negative connotation, although substitution can suggest compromise, experimentation, or a practical workaround. In formal and legal contexts, it may refer to the deliberate replacement of one provision, witness, product, or method with another. As the present participle and gerund of substitute, it also appears in phrases such as “the substituting of local materials for imported ones.” Related forms include the noun substitution and the adjective substitutable.

Substituting starts with a picture of one thing being placed under another: Latin substituere literally meant “put under” or “place” before English narrowed its sense to replacement.

Where does substituting come from?
Substituting is the English present participle and gerund of substitute, formed by adding the suffix -ing. Substitute came through French substitut from Latin substituere, meaning “put under,” “place,” or “substitute,” and was built from sub- (“under”) and stāre (“stand”). The Latin root stāre also underlies words such as substance and subsistence.
