A primitive root; to cramp, i.e. Confine (in many applications, literally and figuratively, formative or hostile) - adversary, assault, beset, besiege, bind (up), cast, distress, fashion, fortify, inclose, lay siege, put up. What does besieged mean? Besieged is defined by the lexicographers at Oxford Dictionaries as (of a place) surrounded by armed forces aiming to capture it or force surrender.
Besieged is a traditional term used to describe the situation of a planet (particularly a significator) placed between two other planets and falling within both of their orbs of influence. The conflicting connotations of the word besieged derive from the tendency of an older generation of astrologers to call attention to conjunctions in which a benefic planet (e.g., Venus) was placed between two malefics (e.g., Mars and Saturn). A planet can be favorably besieged, however, as when placed between two benefic planets.
