致す
いたす
- middle-high (nakadaka): falls after mora 2
How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).
-- extra-modest expression for する --
Itasu is the transitive/causative counterpart to the intransitive verb 至る (itaru).

What Wiktionary says
Quoted line by line from Wiktionary's Etymology section for this reading, taken from one dated dump so it can't change underneath us. Nothing below is paraphrased.
- “From Old Japanese. Derived as the transitive/causative counterpart to intransitive verb 至る (itaru, “to come; to go; to reach a point in time or space; to result in”), originally meaning the same as causative conjugation 至らせる (itaraseru, “to make something or someone come or go; to make something reach a point in time or space; to cause a certain result”).”
