Rule reminder
Many Italian verbs seem interchangeable but are used in fixed collocations with specific nouns. Key distinctions: 'affrontare' (to face/tackle) vs 'risolvere' (to solve/resolve), 'raggiungere' (to reach/achieve) vs 'ottenere' (to obtain/get), 'sostenere' (to support/maintain) vs 'supportare' (to support structurally — not emotionally in formal Italian). Getting these right makes your Italian sound truly fluent.
