T-rules
The T(ea)-rules ("T(hee)-regels"), are a set of conjugation rules used in the Dutch language to determine whether the second person singular/plural and the first and third person singular of a verb end in "-t" or not. These rules are related to the 't kofschip-rule, which is used to determine the verb end for past tenses and participles. The combined sets of rules are also known as the d/t-rules. Second person pronouns. The pronoun "jij/je" only calls for the verb to end in "-t" if it precedes the verb, and if the verb is  in the present simple or present perfect indicative. Modal verbs and the future/conditional auxiliary "zullen" allow forms with and without "-t" (but the subject pronoun must still precede the verb for the "-t" form to appear). If the stem of the verb ends in "-t", the "jij" form always ends in "-t": With the verbs "houden", "rijden" and verbs derived from them, the "-d" of the radical can be dropped if it is not followed by "-t". In a formal context, usually the "d" is not dropped. Section::::"Jullie" (2nd plural). The pronoun "jullie" always makes the verb end in  -en. The ending "-t" is also possible, but this form is archaic (although it does survive in Brabantian dialect). Section::::"Gij/ge" (2nd sing./plur.). The pronoun "gij/ge" makes the verb end in "-t", whether the pronoun precede or follow the verb. Modal and auxiliary forms also end in "-t". This pronoun is used informally in spoken language in North Brabant and Flanders only. Its written form only appears in archaic texts where it compares to English "thou". No extra "-t" is added if the verb stem already end in "-t". The ending "-t" is added after "-d": In the subjunctive  and in the regular past, the "-t" survives only as an archaic form: In informal speech (only in Flanders/Brabant), the verb ends in "-de" or "-te", if "gij" follows the verb. In very informal speech (only in Flanders/Brabant), the subject is dropped altogether. The "-e" ending after the stem is a remnant of the Middle Dutch pronoun "di" which, over the centuries, developed into a clitic. Third person singular and "u"/"U". The rules for third person singular subjects and the pronoun "u"/"U" (2nd person sing./plur.) are the same: the verb takes "-t" in the simple present and present  perfect tense of the indicative. Modal verbs and "zullen" (will) have forms without "-t". This pronoun is formal and is used in both written and spoken language. The spelling with a capital "U" is very formal and is used for royalty or deities. The first person singular for non-modal verb is identical to the radical. The form can end in a vowel or in a consonant (including "t"). For the verbs "houden", "rijden" and their derivatives, the "-d" of the radical can be dropped in spoken language. In a formal context, the "d" is not dropped. T-rules The
