How to check condition with the value of a key in data and also display all the nested values if present

I have the sample mongo document data as (for ref):

The <code>data</code> object passed to the template is as this

from view as:

data=wordscollection.find({'word':word})
return render_template('wordsearch.html',data=data)

In the template I have this just for the first index and doesn't check if example or synonym is empty:

{% for word in data %}
    <tr>Meaning :{{  word['meanings'][0]['def'] }}</tr><br>
    <tr>Example :{{  word['meanings'][0]['example'] }}</tr><br>
    <tr>Parts Of Speech :{{  word['meanings'][0]['speech_part'] }}</tr>
{% endfor %}

which outputs as:

enter image description here

1) How can I display all indexes results as

meaning1: def1
speechpart1: speech_part1
example1:                    //2)writing condition for this to show if exits
synonym:                      //2)writing condition for this to show if exits

Meaning2: def2
........
........

I have tried my luck for 2) as below :

      {% for word in data if word['meanings'][0]['example'] %}

but this didn't work either

Any help is appreciated, TIA

updated answer for synonyms 

    {% for word in data %}
        {% for meaning in word['meanings'] %}

                <tr>Meaning :{{  meaning['def'] }}</tr><br>

                {% if meaning['example'] %}
                    <tr>Example :{{  meaning['example'] }}</tr><br>
                {% endif %}

                {% if meaning['speech_part'] %}
                    <tr>Parts Of Speech :{{  meaning['speech_part'] }}</tr><br>
                {% endif %}
                 {% for synonyms in meaning['synonyms'] %}
                        {% if meaning['synonyms'] %}
                            <tr>synonyms : {{ synonyms }} </tr><br>
                        {% endif %}
                 {% endfor %}
        {% endfor %}
    {% endfor %}

You have to use nested for loop to iterate meanings also and check for empty values before

{% for word in data %}
    {% for meaning in word['meanings'] %}
        <tr>Meaning :{{  meaning['def'] }}</tr><br>
        {% if meaning['example'] %}
            <tr>Example :{{  meaning['example'] }}</tr><br>
        {% endif %}
        {% if meaning['speech_part'] %}
            <tr>Parts Of Speech :{{  meaning['speech_part'] }}</tr>
        {% endif %}
    {% endfor %}
{% endfor %}
