Ter sede

This is a verb-noun collocation. You use the verb ter (to have) with the noun sede (thirst). It's super straightforward! You conjugate ter based on who is feeling thirsty. For example, 'I have thirst' becomes Eu tenho sede. 'She has thirst' is Ela tem sede. It's as simple as that. Just remember to match the verb to the subject. It's like saying 'I have hunger' instead of 'I am hungry' in some languages, but for thirst, this is the natural Portuguese way.

Imagine you're out on a hot day. Your throat is dry. You'd say, Estou com tanta sede! (I'm so thirsty!). Or maybe after a long workout: Preciso de água, estou morrendo de sede. (I need water, I'm dying of thirst). It's used in everyday chats, texts, and even in more serious situations when dehydration is a concern. It's your everyday thirst-quencher phrase.

Use ter sede anytime you feel that physical need for a drink. After exercising, on a sunny day, when you've been talking a lot, or even just waking up in the morning. It's appropriate in almost any casual or semi-formal situation where you'd naturally express thirst. If you just finished a marathon or a TikTok dance session, this is your phrase!

Avoid using ter sede in highly technical or medical contexts where a more precise term might be needed, like discussing specific physiological conditions. Also, don't use it if you're not actually thirsty! Using it sarcastically might work with friends, but it could be confusing otherwise. It's not for expressing metaphorical 'thirst' for knowledge or success, though context can sometimes allow for that playful use.

Learners sometimes try to translate 'I am thirsty' directly using the verb 'to be' (ser or estar). This is a classic pitfall! Another mistake is using the wrong verb with sede, like estar sede or fazer sede. These simply don't exist in Portuguese and sound very odd. Always stick to ter sede or estar com sede.

Estar com sede is a very close synonym, meaning 'to be with thirst.' It's equally common and often used interchangeably with ter sede. Think of it as a slightly more descriptive way to say you *are currently experiencing* thirst. Morrendo de sede (dying of thirst) is a hyperbole, an exaggeration for dramatic effect, used when you're *extremely* thirsty. It’s like saying ‘I’m starving’ when you’re just a bit hungry.

Besides estar com sede, you'll often hear estar morrendo de sede for extreme thirst. Sometimes, people might use estar seco/seca (to be dry), especially referring to the throat, as a shorthand for being thirsty. If you're feeling a bit peckish and thirsty, you might combine it: Estou com sede e fome. (I'm thirsty and hungry). It's all about expressing that physical need.
