СТОЛБ _|_ POST / STOLB [stoɫp]     

Hint with an alternative definition: it is a strong, long and slender piece of steel (metal) or wood, used for various construction or support purposes, it stands still for a long time; for example, it is a tall pole (post, pillar, stob) on the street (with a lamp, a board or wires), it can stop & block a dumbbell person or drunk person on a car, but sometimes it is dog’s toilette 🙂

Hint with a mirror: blots (dirty & low) | столб (high & shining)

Russian pro-tip: стоит + блок

Mental visualization: C (illuminated area of asphalt) + T (lamppost) + O (other illuminated area) + ЛБ (another lamppost that illuminates one side)
