いらっしゃるTo be (Honorific), To come (Honorific), To go (Honorific)

いらっしゃる is another of the common honorific language expressions in Japanese. This means that it elevates the status of another person, in order to pay them respect. It will never be used when referring to the speaker themselves, or their own actions.

いらっしゃる can be used to replace 居(い)る 'to be', 来(く)る 'to come', or 行(い)く 'to go'. This is due to the unique perspective that honorific language places the speaker in, in relation to the person that is being respected. This is a slightly advanced concept that we will discuss more later.

To use いらっしゃる, simply replace いる, くる, or いく with いらっしゃる.

Alternatively, いらっしゃる may also be used to replace いる, くる, or いく when they are attached to the て-form of another verb.

Fun Fact

おいでになる is another expression which can replace いる, くる, or いく. This was briefly examined previously in our お～になる grammar point. おいでになる and いらっしゃる are almost completely interchangable.
