Questions & Answers about Мы часто думаем о работе.
Why is работа changed to работе in this sentence?
Because after the preposition о (meaning about) Russian uses the prepositional case. The nominative работа becomes работе (ending -е).
Why do we use the preposition о here, and when should I use об instead?
The preposition о (about) is used before words that start with most consonants. You use об before words that start with a vowel (e.g. об идее) or certain clusters for easier pronunciation.
Why is the noun in the prepositional case and not the accusative?
Some Russian verbs, like думать (to think), require the prepositional case when indicating what you are thinking about. They never take an accusative direct object in this sense.
Why is the verb думаем ending in -ем? How do you conjugate думать?
Думаем is the first person plural (we) present tense form of the verb думать. Думать is a first‑conjugation verb, so its present‑tense endings are:
я думаю, ты думаешь, он/она думает, мы думаем, вы думаете, они думают.
