Common Mistakes

'insertion' sounds overly formal for simple everyday actions; the gerund 'inserting' is more natural in ordinary speech.
Please do the insertion carefully.

Synonym discussion

Sense: noun/1

Insertion, introduction, placement, and inclusion all describe putting something somewhere, but each has a different focus. Insertion is the most literal — it means putting one thing physically into the body of another (a key into a lock, words into a text). Introduction is broader, covering the act of bringing something new into a system, situation, or practice (the introduction of online payments). Placement is about position and arrangement, without necessarily implying that the thing goes inside something else (the placement of furniture in a room). Inclusion means making someone or something part of a larger group or set (her inclusion on the team). For the physical or textual act of putting one thing inside another, insertion is the most precise choice. For starting something new, use introduction. For deciding where things go, use placement. For membership or belonging, use inclusion.

Etymology

LatinFrenchEnglish

The word 'insertion' comes from Latin 'insertio', meaning 'a putting in'. This was formed from 'inserere' (to put in, implant), which itself combines 'in-' (in) and 'serere' (to join, attach, link together). The word entered English in the late 1500s through French, originally used in formal and medical writing, and later broadened to cover any act of adding something into a text, container, or device.
