A hot tea, please.
TÈ — one syllable, accent on the 'e' to distinguish it from 'te' (you). Rhymes with 'day'.
When you want tea rather than coffee. Italian bars always have tea, though it is a minor item compared to espresso.
'Tè caldo' specifies hot tea — because 'tè freddo' (iced tea) is also common. Italian bars usually offer basic tea bags (Lipton is standard). For better tea, seek out specialist shops or English-style cafés.
Un tè al limone.
A lemon tea.
The classic Italian tea order — lemon rather than milk is the default
Un tè alla menta.
A mint tea.
Herbal option — often served as 'tisana alla menta' in more specialist bars
Una tisana alla camomilla.
A chamomile tea.
'Tisana' = herbal infusion — chamomile ('camomilla') is the most popular Italian herbal drink
Tea is not part of Italian coffee culture but is widely available. Italians drink tea mainly when ill — 'una camomilla' (chamomile) is the Italian remedy for everything from stomach ache to insomnia. Offering someone a camomilla is also a gentle way of saying they need to calm down.
