Alternating Actions with "то ..., то ..."
When you want to describe actions or states that rapidly alternate, Russian uses the correlative conjunction то ..., то .... It translates to "now ..., now ...", "first ..., then ...", or "one moment ..., the next ...".
This structure is perfect for describing unpredictable behavior, like a child acting up (капризничать) or someone constantly changing their mind (передумывать).
| The child is acting up today: now he cries, now he laughs. | Ребёнок сегодня капризничает: то плачет, то смеётся. |
| She changes her mind all the time: first she wants to go to the park, then to the cinema. | Она постоянно передумывает: то хочет пойти в парк, то в кино. |
Physical States and Reactions
You will frequently use this paired conjunction to contrast rapidly changing physical sensations, such as freezing and sweating, or to describe someone's wildly fluctuating reactions and mood swings.
| I am sick: now I freeze, now I sweat. | Я болен: то мёрзну, то потею. |
| The director now scolds, now praises the manager. | Директор то ругает, то хвалит менеджера. |
Fluctuating Environments and Technology
This pattern isn't just for people. It is very common when talking about shifting environmental conditions or unstable technology, like weather that changes by the minute or signals that appear, blink (мигать), and vanish.
| The weather is strange: the sun now shines, now disappears. | Погода странная: солнце то светит, то исчезает. |
| The signal on the phone either disappears or blinks. | Сигнал на телефоне то исчезает, то мигает. |
