Copy values from choice to managed metadata field

PowerShell Help
1

Hi, i have powershell where i’m getting values from choice field, then i join these vaules from this field with string. I’m doing it because i need copy values from choice to Managed metadada field.
Code:
foreach($varItemLanguage in $varitem.Language){

    $varLanguage = "Site Collection - mysitecollection|Language|"+$varItemLanguage;
    Write-Host "Item LAnguage:"$varItemLanguage
    Write-Host "LAnguage:"$varLanguage
    $varLangArray +=  $varLanguage+" "
    write-host "Array: "$varLangArray
}

for first item it works properly and outputs:
Site Collection - mysitecollection|Language|PL Site Collection - mysitecollection|Language|DE and then i put this value to managed metadata column.
For 2nd object it outputs
Site Collection - mysitecollection|Language|PLSite Collection - mysitecollection|Language|DE and then PnP shows warning that term not found.
Please help

If I got you right this should be enough:

$varLangArray =
foreach($varItemLanguage in $varitem.Language){
    "Site Collection - mysitecollection|Language|{0} " -f $varItemLanguage
}
$varLangArray
