よくある間違い：
Learners often confuse "indicator" and "indication". Use "indicator" mainly for a sign that can be used as a measure (often countable and systematic, e.g., "economic indicators"), and "indication" for a more general sign or hint. Learners also sometimes say "indicator for" instead of the more natural "indicator of".
