Context does the work English gives to articles and plurals. When number matters, Japanese adds a number and a counter: 本を二冊, “two books”.
Short answer: these 60 words cover the people, places, things and actions of an ordinary day, and you can build hundreds of sentences from them. Japanese nouns do not change: there is no “a” or “the”, and 本 hon means book or books. Verbs and adjectives do change their endings, so each verb here is shown in its dictionary form and its polite ます form.
People, places and things
Six of each to start. Many everyday nouns are two-kanji compounds read with on readings, like 学校 gakkō; short native words such as 家 ie use kun readings.
People
Places
Things
Ten everyday verbs
Japanese verbs come at the end of the sentence. The dictionary form is how you look a verb up and how friends speak; the ます form is the polite form you will use with everyone else at first.

Adjectives
Japanese has two kinds of adjective. Most end in い and change their ending (い-adjectives); others take な before a noun (な-adjectives). The last two below are な-adjectives.
Time words
Several time words have special readings that do not follow the kanji: 今日 is kyō, not kon-nichi. Learn them as whole words.
Question words
With these six words and the question particle か you can ask about anything.
Tomodachi to gakkō ni ikimasu.“I go to school with a friend.”Why:と means “with” after a person; に marks the destination. “A friend” or “friends”: context decides.
今日kyōtodayはwa(topic)時間jikantimeがga(subject)ありますarimasuthere is
Kyō wa jikan ga arimasu.“I have time today.”Why:Japanese says “as for today, time exists”. あります is used because time is not a living thing.
Sensei ga wakarimasu.“The teacher understands.”Why:が marks who does the understanding. With 分かる, the thing understood also takes が, which you will meet later.
