Every SYN corpus contains all the synchronic written corpora of the SYN series published up until the time of the given version's publication. The corpus SYN version 11 therefore contains the SYN2000, SYN2005, SYN2006PUB, SYN2009PUB, SYN2010,SYN2013PUB, SYN2015 and SYN2020 corpora; additionally, it contains a journalistic component predominantly from 2010–2020 (already included into SYN version 4 – SYN version 10) corpora, and as yet unpublished journalistic texts from 2021 in yearly volume almost 150 mil. words.
The SYN corpus is not representative; the dominant component is journalism, which is the result of the predominance of journalistic corpora SYN2006PUB, SYN2009PUB, SYN2013PUB and the journalistic component from 2010–2021.
The SYN version 11 corpus is referential, and will remain accessible to users even after newer versions have been published. It is however necessary to keep in mind that the linguistic information will become outdated, as a natural result of the referential nature of the corpus. Individual versions of the SYN corpus will continue to be published regularly every year with the addition of current journalistic data, and every new addition will be given the attribute value <doc syn> equal to the version of the SYN corpus in which the given text first appeared; for example a subcorpus corresponding to the above mentioned (as yet unpublished) journalistic component can be created from the SYN version 11 with the help of the condition syn="v11".

Journalism in SYN version 11
The composition of the journalistic part of SYN version 11 covers the production of most of the national daily newspapers (Mladá fronta DNES, Lidové noviny, Právo, Hospodářské noviny, Blesk, Sport), regional daily newspapers (chiefly Deníky Bohemia and Moravia published by Vltava Labe Media) and non-specialized magazines (Reflex, Respekt, Týden) from 1998–2021; the total number of journalistic titles is almost 200. The following graphs show the composition of the SYN corpus based on the main text types over the years and offer a closer look at the composition of the journalistic section.
Structure and annotation of SYN version 11
Generally speaking, structure and annotation of SYN version 11 are based on that of the SYN2020 corpus. In particular, hierarchy of structural tags for SYN version 11 has been taken over from SYN2020, as well as the lemmatization and morphological tagging. In this respect, SYN version 11 is the same as its predecessor, SYN version 10.
The correspondence of structure and annotation between SYN version 11 and SYN2020 only has the following exceptions:
* introducing the additional attribute <doc syn> for the creation of subcorpora corresponding to the original reference corpora;
* replacing syntactic annotation in the SYN2020 corpus with a pilot version of phraseme annotation**.
