Your question is a little bit complicated to me, but do you mean a *[self-referencing][1]* word? If so, then it is usually called an [autological word][2] or an autonym. ---------- **[Autogram][3]** - A sentence that describes itself in the sense of providing an inventory of its own characters. >This sentence has five words. >This sentence contains nine syllables. ---------- **Reflexive** (sentence) A sentence where the subject and object are the same (Sources: Reflexive [verb][4], [pronoun][5]). >The man washed himself. ---------- **[Hofstadster's Law][6]** Hofstadter's law is a self-referential time-related adage, coined by Douglas Hofstadter and named after him. > Any task you're planning to complete will always take longer than expected - even when Hofstadter's law is taken into account. **Even if you know a project will overrun, and build that knowledge into your planning, it'll simply overrun your new estimated finish time, too**, Hofstadter says. (Source: [The Guardian][7]) ---------- [Post hoc ergo propter hoc][8] Latin for *after this, therefore because of this*. It means a logical fallacy (of the questionable cause variety) that states "Since event Y followed event X, event Y must have been caused by event X." Sometimes shortened **post hoc**. >The server was working fine until you started working here. Therefore, you must be the reason why it's broken. ---------- **[Recursion][9]** Recursion is the process of repeating items in a self-similar way. (Warning: Has many applications outside of language as well.) >To understand recursion, you must understand recursion.
