TypeError: translator () missing 1 required positional argument: 'word'

esoty doing a practice of python but I have run into a problem when running the code

import json
from difflib import get_close_matches
from flask import Flask, render_template
from flask_bootstrap import Bootstrap

app = Flask(__name__)
Bootstrap(app)

collection = json.load(open("collection.json"))

@app.route('/')
def home():
    return render_template('home.html')

@app.route('/nosotros')
def prueba():
    return render_template('nosotros.html')

@app.route('/traductor')
def traductor(word):
    if word in collection:
    return collection[word]
elif len(get_close_matches(word, collection.keys())) > 0:
    yn = input("Quizas estas buscando esta palabra %s ? Presiona S 
para si o N para No:b" % get_close_matches(word, collection.keys())[0])
    if yn == "S":
        return collection[get_close_matches(word, collection.keys())[0]]
    elif yn == "N":
        return "Palabra no encontrada. Por favor busca de nuevo."
    else:
        return "No has escrito ninguna palabra"

print('\n***** Bienvenido al Diccionario KUNA *****\n')
word = input("Escribe tu palabra:  ")
output = traductor(word)
if type(output) == list:
    for item in output:
        print(item)
else:
    print(output)
return render_template('traductor.html')

if __name__ == '__main__':
app.run(debug=True)

If you could indicate me if it is an argument failure or how the request is built

Here are the logs:
