Sentence:  Simply put, <WSD>entelechy</WSD> is any process that has a beginning, middle, and end. The end or goal is the "telos"; it shows up as the second syllable of the word en-TEL-echy. A simple natural <WSD>entelechy</WSD> is the corn <WSD>entelechy</WSD>. A kernel of corn when planted begins an <WSD>entelechy</WSD>. That is, a process of growth begins as the kernel/seed sprouts roots, then a blade. The growth process continues until it reaches its "telos". Its "telos" is the completion of the process and the resulting production of brand new kernels that look very much like the kernel that began this process. Once that "telos" or goal has been reached, we say that the process is complete or perfect or "teleios". But then what happens? A new <WSD>entelechy</WSD> begins. Each of those kernels that were produced in the previous <WSD>entelechy</WSD> begins to sprout and produces its own <WSD>entelechy</WSD>. In other words, <WSD>entelechies</WSD> are often cyclical. 
Meaning of the word marked with <WSD> tags:  The complete realisation and final form of some potential concept or function; the conditions under which a potential thing becomes actualized.
