Ligate and insert are not synonymous.
Ligate typically refers to the act of tying or binding something, often in a surgical or biological context. For example, a surgeon might ligate a blood vessel to stop bleeding. Ligation involves closing off or fastening something tightly.
On the other hand, insert means to put or place something into something else. It could be inserting a key into a lock, inserting a new paragraph into a document, or inserting a gene into a DNA sequence. Insertion is about adding something within or between other things.
In summary, while both words involve some action related to placing or manipulating objects, they have distinct meanings. Ligate is about binding and closing, while insert is about putting something into a particular location or space.
