Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'соседство' when referring to abstract or logical connection—it's too informal. 'Смежность' or 'примыкание' are closer for physical/logical contexts.
- The plural 'adjacencies' does not map neatly to a standard Russian plural; it's a technical term best translated per context (e.g., 'смежные участки', 'прилегающие зоны').
Common Mistakes
- Using it as a countable noun in general contexts (e.g., 'They share an adjacency' – awkward).
- Confusing it with 'adjacent' (adjective) and saying 'in adjacency to' instead of the more natural 'adjacent to'.
- Misspelling as 'adjacancy' or 'adjacence'.

FAQ
Frequently Asked Questions
No, it is a low-frequency word used mainly in formal, academic, technical, and business contexts. In everyday speech, people use 'closeness', 'nearness', or simply 'next to'.
Often, but not always. 'Proximity' is broader, meaning 'nearness in space, time, or relationship.' 'Adjacency' strongly implies sharing a common border or being immediately next to, often in a more precise or technical sense.
The plural is 'adjacencies'. It is used in specialized professional jargon, such as in broadcasting to refer to commercial slots next to specific programmes, or in real estate to refer to adjoining parcels of land.
The main adjective is 'adjacent', meaning 'next to or adjoining something else.' It is far more common than the noun 'adjacency'.
