Pro Tip

Avoid redundancy

Do not pair 'perilous' with 'very' (e.g., 'very perilous'). Instead, use 'extremely perilous' or choose a stronger synonym like 'hazardous'.

Gold Rule

Context matters

Use 'perilous' for situations involving serious, often life-threatening danger, not minor risks.

Word Origin

From Middle English 'perilous', from Old French 'perilleus', derived from Latin 'periculosus', from 'periculum' (danger), related to 'periri' (to try, risk).

Usage Notes

Used in formal contexts to emphasize significant danger. Avoid using in casual speech where 'dangerous' or 'risky' would suffice.
