Symfony - Twig - Dynamic variable - How to concatenate two variables in a loop

Question

I have to concatenate two variables in one, beside the request.locale

I explain to you :

I have an Entity named Lexicon with several field: wordFr, wordEn, definitionFr, definitionEn

I tried to do something like that for replace the Fr or En according to the request.locale but it doesn't work :

             {% set locale = '' %}

             {% if app.request.locale == "fr" %}
                 {% set locale = 'Fr' %}
             {% else %}
                 {% set locale = 'En' %}
             {% endif %}

             {% for wordList in wordsList %}
                 <tr>
                     <td>{{ wordList.word~locale }}</td>
                     <td>{{ wordList.definition~locale }}</td>
                 </tr>
             {% endfor %}

How to have {{ wordList.wordFr }} or {{ wordList.wordEn }} according to the locale (replace var locale by Fr or En) ? thanks !

In the meanwhile I did this but it's too long and repetitive...

                {% if app.request.locale == "fr" %}
                    {% for listeMots in listeMotsLexique %}
                        <tr>
                            <td>{{ wordList.wordFr }}</td>
                            <td>{{ wordList.definitionFr }}</td>
                        </tr>
                    {% endfor %}
                {% else %}
                    {% for listeMots in listeMotsLexique %}
                        <tr>
                            <td>{{ wordList.wordEn }}</td>
                            <td>{{ wordList.definitionEn }}</td>
                        </tr>
                    {% endfor %}
                {% endif %}

What you want is to use the Twig attribute function which is documented here.

It allows you to use dynamic variable names. You would have to do something like that:

{{ attribute(wordList, 'mot'~locale) }}

You're basically saying that you want the 'mot'~locale from the wordList object
