如何将pandas中的行与每行的第一个单词相加为该第一个单词的聚合值？

import pandas as pd

data = {'Text': ['apple banana cherry', 'orange grape', 'kiwi lemon']}
df = pd.DataFrame(data)

def aggregate(row):
    words = row.split()
    return words[0] + str(len(words))

df['Aggregated'] = df['Text'].apply(lambda x: aggregate(x))

print(df)

                 Text Aggregated
0  apple banana cherry       apple5
1        orange grape      orange2
2          kiwi lemon        kiwi2
