Usage notes
The verb "to substitute" can be used transitively in two opposite ways. "To substitute X" may mean either "use X in place of something else" (as in definitions 1 and 2), or "use something else in place of X" (as in definitions 3 and 4). The latter use is more recent, but it is widespread and now generally accepted (seethe COED's note on the matter). However, if the indirect object (the "something else") is omitted, the preposition is also omitted, and the reader or hearer cannot tell which sense is meant: * "Substitute butter for olive oil" = Use butter instead of olive oil * "Substitute olive oil for butter" = Use olive oil instead of butter * "Substitute butter" = ??? * "Substitute olive oil" = ???
