# How to decline citation using biblatex?

In Finnish language we need to decline words. So how to do this when I do textual citation? I would like to use some custom command like \customcitet[Greenwaden]{greenwade93}. I would appreciate solution without conflicts with biblatex (with natbib commands) package.

Here is minimal example:

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents}{bibfile.bib}
title   = "The {C}omprehensive {T}ex {A}rchive {N}etwork ({CTAN})",
year    = "1993",
journal = "TUGBoat",
volume  = "14",
number  = "3",
pages   = "342--351"
}
\end{filecontents}
\usepackage[%
natbib,%
authordate,%
backend=biber,%
noibid,
language=finnish,%
]{biblatex-chicago}
\bibliography{bibfile}
\begin{document}

But I want something like this: Greenwaden (1993).
\end{document}


• I cannot see any difference in your example... – Yorgos Dec 7 '16 at 21:00
• @Yorgos - "Greenwade" vs "Greenwaden" – Nathan Musoke Dec 7 '16 at 21:46
• @Lesenger -- we could probably close this question unless you are still hoping for a inflection-sensitive custom \cite key. What do you think? – jon Dec 8 '16 at 16:00
• Until and unless natural language analysis becomes way more sophisticated, no software system can reliably pick up which declension form should be used. The situation is comparable to that in the cleveref package, which generates "clever" cross-references: The label prefixes generated by \cref ("section", "figure", theorem", etc) are all in nominative form, for every language localization. If you happen to write in a language that declines nouns, you simply mustn't use \cref if the noun isn't in the nominative form. Instead, write out the correct form of the noun plus \labelcref. – Mico Dec 8 '16 at 16:35
• @jon yes we could. This question didn't end up being so helpful, but if someone knows an article about language localization in tex, maybe it could be linked to this question. – Lesenger Dec 8 '16 at 22:48

Edit

From the comments, it turns out that all that a satisfactory answer is to type out the name of the author in the appropriately inflected form and then use \parencite*{<entrykey>}.

Original suggestion

Here's one way to do it.

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents*}{bibfile.bib}
@preamble{ "\newif\ifdecline" }
@preamble{ "\newcommand\finale{\ifdecline en\else e\fi}" }
author  = {George D. Greenwad\finale },
title   = {The {C}omprehensive {T}ex {A}rchive {N}etwork ({CTAN})},
year    = {1993},
journal = {TUGBoat},
volume  = {14},
number  = {3},
pages   = {342--351}
}
\end{filecontents*}
\usepackage[%
natbib,%
authordate,%
backend=biber,%
noibid,
language=finnish,%
]{biblatex-chicago}
\bibliography{bibfile}

\newcommand\dcitet[1]{\AtNextCite{\declinetrue}\citet{#1}}

• Command where I could manually write whole authors name like \customcitet[Greenwaden]{greenwade93} would be best I think. If that is not possible, I could write manually whole citation Greenwadenilla (1993) but I'd like bibliography/reference list to autamatically update. – Lesenger Dec 7 '16 at 22:44
• Most simple solution I come up with is just use Greenwadenilla (\citeyear{greenwade93}). Hyperref doesn't seem to work, but citeyear command at least adds item to bibliography. – Lesenger Dec 7 '16 at 23:06
• Well, I can't actually answer your question if you don't provide the required details. (You didn't even mention hyperref..!) I have to point out that typing \customcitet[Greenwaden]{greenwade93} is not more efficient, and far more error prone, than a simple Greenwaden \parencite*{greenwade93} (which will also work with hyperref by default). So I'm not sure your proposed solution to a still unclearly-defined question is worth pursuing. – jon Dec 7 '16 at 23:30
• Sure, but you suggested only two declensions were needed; later, many more were needed (and I don't know Finnish). If there are only two, a simple conditional will work; if several were needed, I would've suggested something different. Your question also implied that a non-manual solution was wanted because it was always an option to simply write a name outside of the \cite command. I appreciate -- very much! -- the fact that you made a minimal example; but aspects of it were perhaps too minimal some some people, like me. – jon Dec 8 '16 at 1:26
