Etymology
The word 'ken' originates from the Old English verb 'cennan', meaning 'to declare, make known', which is related to 'cunnan', meaning 'to know'. These Old English terms derive from the Proto-Germanic root kannijaną ('to make known') and ultimately from the Proto-Indo-European root ǵn̥néh₃ti ('to know'). The semantic journey saw a shift from the active sense of 'making known' to the passive state of 'knowledge' or 'recognition'. In Middle English, it evolved into a noun signifying the range of one's sight or knowledge, a meaning preserved in modern usage, particularly in Scottish English and set phrases like 'beyond one's ken'.
Analysis
The word 'ken' is a simplex word of Germanic origin. It functions as a whole, unanalyzable unit in modern English.
