For example, compare "I will do it myself," where "myself" is a self-intensifier indicating that nobody else did it, to "I sold myself," where "myself" fills the argument role of direct object.
Latin has a dedicated intensifier, ipse, -a, -um, used to emphasize a noun or pronoun in either a subject or a predicate of a sentence.
When a verb is used that requires reflexion, it becomes similar to English except that two words are used: "I help myself" is rendered Jeg hjælper mig selv.
In Spanish, as in most other pro-drop languages, emphasis can be added simply by explicitly using the omissible pronoun.
French uses a form of the disjunctive pronoun that is followed by the adverb -même (e.g. Je l'ai fait moi-même.).
