I type in two languages regularly - depends on who I communicate with, in perhaps 60:40 or 70:30 ratio. Sometimes I even use words from both languages in the same text. Both languages are supported by Swype. But I can only select one of them at one time, so when I need to type in the other language I have to change the settings, which is quite inconvenient. Can I merge two dictionaries or activate both of them at the same time?
You could also try to just add the words you use most of the time, even it is from a different language.
That is what I do. When I'm using one language, and I need a word that is available in the other language, I just type it and add it to my personal dictionary. Over time I will have two dictionaries who will probably both have the words I use the most.
Swype from swype symbol to q to quickly change between two most recently used languages.
Another Stackoverflow question about using multiple keyboards on Android: https://stackoverflow.com/questions/20197421/adding-a-second-dictionary-to-the-spell-check-in-android-4-3/44033793#44033793
Here is how for example to have a French keyboard with French dictionary + French keyboard with English dictionary
Android settings > Language & Input > Gboard (Google default keyboard).
Languages, you can tick all the keyboards you want. In my case,
French (France) and
This will give you the usual AZERTY French keyboard and the usual QWERTY English keyboard.
If you want the English dictionary with a French AZERTY keyboard, you can go to
Preferences > Personalised input styles and create a new keyboard
Language: English (UK) Layout: AZERTY, then in the
Languages menu, you will have a new keyboard in the list,
English (UK) (AZERTY). Tick it.
You now have 3 keyboards in your list:
English (UK) and
English (UK) (AZERTY).
While using the keyboard, you can then switch from one keyboard to another either with the special button or by holding the
Space bar. The
Space bar also shows the current language being used.
Using multiple dictionaries at the same time: In
Text correction, there is an option called "multilingual suggestions", this will use several dictionaries at the same time, recognising as valid all words from the selected languages. If active, the
Space bar will show something like FR-EN, to indicate that several languages are active at the same time. I personally don't like it.
