Dictionary Form/ます Form of a Potential Verb
As you know, English tenses are roughly divided into present, future, and past tenses. However, it is said that Japanese tenses consist only of “Past Tense” and “Non-Past Tense.” Therefore, we used “Dictionary Form,” not “Present Tense” in this heading.
Japanese people use two types of language. One is “non-honorific language” and the other is “honorific language.” When we focus on these languages, “dictionary” and “plain” forms are in “non-honorific language.” “Polite form” is in honorific language.
English Meaning: can buy/(will) be able to buy

「辞書形 (dictionary form)」is the original form. The technical term is for non-native Japanese speakers. Therefore, native Japanese usually do not know the word.「ます形 (ます form)」is the polite form of a dictionary form. The term is also for non-native Japanese speakers.
