Used predominantly in singular form ('a nexus', 'the nexus'), but plural can be 'nexuses' or, less commonly, 'nexus' (treating it as a Latin neuter noun).

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as simple 'связь' (svyaz') or 'узел' (uzel) without considering the formal and structural nuance. 'Нексус' is a direct loanword used in similar contexts. 'Фокус' (fokus) or 'центр' (tsentr) can be closer conceptually.
Common Mistakes
- Using it as a casual synonym for 'link'. Incorrect pluralisation (e.g., 'nexi' is not standard; use 'nexuses'). Confusing it with the brand name 'Nexus' (phones, tablets).
