Having analysed selected Baroque texts (mostly fiction), grammar books and dictionaries, I found that in the Baroque Czech there are the following
expressions usually called intensifying / gradational by traditional Czech syntactic theories.
I) Conjunctions:
1. Simple (i.e. consisting of only one part; "jednodílné") ano, ba; anobrž, nýbrž (rarely having the intensifying meaning, mostly adversative);
2. Partioned (i.e. a pair of conjunctions which work together to coordinate two items; "různovětné"): netoliko / nejen(om) / nercili / neřkuli(c) ale / nýbrž / anobrž / alebrž / než / ano / ani (like the Latin pattern non solum / non tantum / non modo sed etiam / verum etiam, the Czech structure is lexically variable).
II) Modifiers (usually following the conjunctions):
1. Adverbial expressions nad to / nadto, k tomu;
2. Expressions containing the feature of quantity / intensity: více / víceji, spíše, mnohém;
3. Emphasizing particles: i, ani, také, ještě.
In the Baroque Czech the conjunction nato? and the modifier navíc are not used at all. The expression dokonce keeps its original quantitative / totalising meaning in most cases. The analysis of Baroque Czech conjunctions shows that with regard to their meaning these intensifying expressions do not share any intensifying features, i.e. they do not form a homogeneous group in this respect. In my analysis I have also found that in the Medieval period the influence of German syntax on Czech syntax increased: 1) The German affirmative ja that changed into an intensifying conjunction also influenced the Czech affirmative ano, ba, which became an intensifying conjunction as well. 2) Similarly, the German nicht allein sondern inspired the expansion of the Czech conjunction nýbrž into netoliko / nejen(om) nýbrž.
