sister
Transitive Verb[C] Countable
pl: sisterspast: sisteredpp: sistereding: sistering
The word carries a strong emotional weight of kinship and shared history. While it denotes a biological relationship, it is frequently used to describe deep, lifelong bonds of loyalty and mutual support regardless of blood relation, often appearing in social or political movements to signal solidarity. In a religious context, the term shifts from a familial bond to a spiritual one, designating a shared devotion and a communal life within a convent. This usage implies a vow of service and a surrender of individual autonomy to a higher calling.
Countable when referring to individual female siblings or nuns.
